I agree that the sentence is grammatically correct, but it's waaaaay out of the realm of normal conversation. Such sentences are difficult for learners because when you you come up with your best translation and it still sounds clunky, you think it must be wrong.

It doesn't sound like awkward grammar and syntax (AKA sentence structure and a choice of words that suits that sentence structure). What is objectionable is that the meaning of the sentence is outlandish. This being said, since we all know that the sentences are put together by a logarithm, I urge all of us DL users to just get on with it, taking the sentence for what it's worth. And what it's worth is that we get to learn Spanish for free.

Wouldn't that be: "In the past, they didn't know how to swim?" OR "They don't know how to swim." If you qualify it as, "in the past," I don't think present perfect works.

The present perfect is used to talk about something that happened in the past which has a significance in the present. So any new situation which is affected by or changes this past circumstance is appropriate. So ANY time you see the present perfect you need to posit that relevance. Of course there is also a chance that you mean to bring that into the future. For example. Our students are preschoolers. They have not known how to swim in the past, so why would you recommend a swimming outing.

I did. I said that at school the sentence was "they couldn't swim" and in the French lessons we had to translate that first into "they did not know how to swim" Your sentence goes according to the motto: why make it simple, when you can make it complicated?

With all respect to you and your French lesson, "they couldn't swim" and "they did not know how to swim" do not mean the same thing. The knowledge to do a thing is not necessarily the ability to do it.

Secondly, by "rationale or authority" I meant a reason or grammatical rule somehow not to use the present perfect (PP) with the verb "know;" I'm sorry, but "He has known how to swim since he was 6 years old" is just as valid grammatically as "He has lived in the United States all of his life."

Thirdly, your aphorism has no bearing here; "have not known" is not more complicated than "did not know," and even if it were, again, simple past tense and present perfect do not carry the same meaning. For example, before the death of a famous Supreme Court Justice last week, we could say "He has lived in the United States all of his life." Today we can no longer say that, but must say (simple past), "He lived in the United States all of his life."

Finally, if the PP meant the same thing as simple past, if PP were more complicated than simple past and if "complication" were a reason to choose one form over another, then we could just dispense with the PP altogether. The above example, I think, demonstrates why we don't do that.

Muddgirl. That makes Duo's answer a fragment of a phrase that only makes good sense with the addition of a 'in the past' or 'because... before' clause. It is clumsy, it is awkward and with a little thought a far better example could have easily been found - but 4 years later, it's still in here!

Four years later, it's still here, and that is as it should be. Why? Because in all that time, not one complainer has offered any solid grammatical reason from any authority as to why it is wrong to say or, more broadly, why the present perfect can't be used with the verb "to know." In fact, there is none.

While it is true that clarifiers like 'in the past" or "until now" are often used with the present perfect, they are not actually necessary, especially in the context of a conversation where the time frame is understood. Therefore, Duo's given translation is certainly NOT a "fragment of a phrase." By definition, it is a complete sentence having a subject (they), a verb (have not known), and an object (how to swim.)

There is nothing at all wrong or clumsy about using present perfect tense here.

Suppose, using muddgirls's example, Teacher B were to say, "In the past, they haven't known how to swim."

Or, possibly, "Until now, they haven't known how to swim."

Either of those is not only grammatical, but not even remotely "clunky."

Conversationally, we tend to speak informally, with frequent use of contractions. Maybe a lot of this grousing about "clunkiness" is rooted in our taking the Owl's raw English translations as presented, rather than the way we would actually say them.

Yes, well, certainly. With only 278,000,000 hits on Google for the exact phrase "have not known", then, obviously, a person to whom this would sound proper could not be a native speaker, right?

In large measure, 'clunkiness' is a matter of what you're accustomed to hearing — or not. In this case, it certainly has nothing to do with proper usage.

You know, one of the strengths of English has been its great flexibility in expressing things, a feature probably derived from its bifurcated W. Germanic and O. French roots. This, contributing to the fact that we can say things in so many different ways, is one of the reasons it's so hard for DL to cover enough alternate English translations to please everyone. But then, maybe, given that television and other media are homogenizing the language down to its lowest common denominator(s), that won't be a problem for much longer, and all 1.2 billion English speakers will soon be saying everything in exactly the same way...to avoid being "clunky". Won't that be grand?

(And , yes, Suezq, I am a native speaker and have been at least as long as you have. ;-)

Invoking the Google incidence of a phrase in isolation, such as "have not known", doesn't help to clarify how a phrase in context such as here ("have not known" + infinitive verb) would be properly translated into English.

Without a qualifier such as 'for a long time', the English translation above is undeniably awkward, if not wrong. One can say "I have seen him swimming" and "I saw him swimming" and they can mean the same thing, i.e. both can have perfect and imperfect meanings and the difference would only be made clear by a qualifier. "I've seen him swimming here every day." "I saw him swimming there once."

Is there any native speaker who would say, "I have known how to swim" (or knit or dance the tango)? Ranting about the putative homogenization of English (which is also debatable, considering the richness of dialects, immigrant varieties, slang, etc.) makes it sound as if you'd like to harken back to the days of classically-inspired prescriptive grammars, which encouraged people to construct their English as if it were Greek.

The purpose of any language is clarity of communication. If the grammar is correct but inelegant, as this phrase is, it does not fulfill its purpose. Complaining that clear and elegant grammar is somehow the purview of "the lowest common denominator" is bizarre. There are much better ways to phrase this sentence and I don't know an English teacher who would allow this phrase without asking it to be restructured. If it was a common idiomatic phrase used in Spanish, as some of the more unusual constructions are, there would be no problem, but unless Spanish speakers use having swimming knowledge as a euphamism, it is, as everyone else has said, extremely clunky.

I think your Google hit count is a bit misleading. In England, it would be typical to say they 'have not known' before abstract nouns such as love, poverty etc.

'In the past' or 'until now' are not actually needed to make sense of the sentence: "they haven't known" in itself tells you (1) that the condition of not knowing began at sometime in the past and (2) that the condition is still in effect at the time of utterance. That;s what the present perfect does.

Present perfect isn't used with the time expression "in the past". In that example the simple past would suffice since the action started and ended in the past. There's no connection with the present, hence why it's called "present" perfect.

Chronosparks: Non-specific time expressions such as 'in the past', 'in the last year', 'until now', 'before now', etc. are precisely the kinds of references to time that can be used with the Present Perfect.

Specific expressions such as 'last year', 'last week', 'when I lived in ...', 'at that time', and the like, cannot, however, be used to modify the Present Perfect and require the simple past tense. Perhaps that is what you meant.

See this: http://www.englishpage.com/verbpage/presentperfect.html

Also, to say that the PP has "no connection with the present," [ as in 'never'] is a bit off the mark as well and that is not why it's called Present Perfect.

As noted by the following quote found at this link:

http://grammar.ccc.commnet.edu/grammar/tenses/present_perfect.htm "This tense [Presesnt Perfect]indicates either that an action was completed (finished or "perfected") at some point in the past or that the action extends to the present:

  • I have walked two miles already [but I'm still walking].

  • I have run the Boston Marathon [but that was some time ago].

  • The critics have praised the film 'Saving Private Ryan' since it came out [and they continue to do so].

Try again to read my second paragraph: "Specific expressions such as 'last year' . . . cannot, however, be used to modify the Present Perfect" . . . and require the simple past tense.

Yes, "last year" is specific; "in the past" is not specific.

And how did I misunderstand your post when you wrote "There's no connection with the present..."?

... and "Present perfect isn't used with the time expression 'in the past' "? (Which, by the way, is just flatly wrong.)

Agreed, but I think this is just a case of DL opting for a literal translation over a natural one. The alternative answer "They have not learnt/learned to swim" is accepted, and I believe this should be the primary translation. Here's why:

In English we say "They know how to swim" and "They do not know how to swim" but "They have not known how to swim" just sounds weird. More naturally we change the verb to "learnt/learned" giving us "They have not learnt how to swim."

In Spanish this verb change is not necessary. They can say "Saben nadar" and "No saben nadar" and "No han sabido nadar."

So the change is an idiosyncrasy of English that Spanish does not have to follow. DL may have chosen not to use "learnt" in the primary translation because inevitably this would result in people saying, hang on, shouldn't that be "No han aprendido a nadar"? But, for me, I'd prefer natural over literal any day.

In Spain, this would be understood as "They didn't know how to swim.", which sounds better than the direct translation of the above Spanish sentence into English. They have a preference for the 'pretérito perfecto compuesto' form over the 'pretérito perfecto simple' form. You would more likely hear "¿Qué has dicho?" ("What have you said?", but better localised as "What did you say?") than "¿Qué dijiste?" ("What did you say?") in Spain.

"They didn't know how to swim" is just simple past isn't it? Past perfect would be uh, "They had not known..." i believe.

Think about present progressive/continuous. In English, it's used for pretty much anything that's ongoing. In Spanish it's only used to emphasize that this is what is occupying my time (or whoever/whatever is the object), as explained towards the end here http://www.studyspanish.com/lessons/presprog.htm .

I think it's a little subtler with past perfect though.

https://www.duolingo.com/RositaLW

That is something that novice language learners most often do not understand. It is quite common to find tenses and expressions that just cannot be directly translated into another target language because there is no direct equivalent or the options are ambiguous.

There are also things that do not translate because they are not part of the social customs of the target language. An example being the use of Miss, Mister and Mrs as stand alone polite titles in some languages while being rude if used in another where the polite custom is to omit them entirely.

The Spanish past tenses are very hard to find exact equivalents for in English.

For example: Ha habido un accidente: There has had an accident. -- becomes- - There has BEEN as accident. - - which used the verb TO BE in English.

This is a really weird sentence to put in perfect tense. Either they didn't or they don't - "have known" somehow implies you're done knowing it.

I wonder if it's throwing off English speakers to not hear the contraction. Does "They haven't known how to swim" (for a long time) sound better?

4/13/2017, 12:59:19 AM

https://www.duolingo.com/JamesCaulfield1

Saber is a tricky word when used in the past tense. In the imperfect past tense, it correlates with the common English understanding of the verb "to know" (e.g., yo lo sabia = I knew it; ella sabia nadar, pero se le ha olvidado = she knew how to swim but she has forgotten).

However, because the perfect past essentially implies that an action has been singularly begun and completed at a time in the past, the word saber actually translates into English more precisely as "to find out". This is because in the perfect preterite you are basically saying you had no knowledge of something and then suddenly you had knowledge, with the act of gaining knowledge coming to completion. For example in Spanish you can say "Yo estuve en el trabajo cuando SUPE que mi padre habia muerto" I was at work when I FOUND OUT that my father had died. You couldn't really translate it as "when I knew that my father had died" because in English that would be a little ambiguous and seem to suggest that you have psychic powers or something.

By extension, the example attached to this page is a little more coherent in Spanish than the translation lets on because it kind of suggests that the girls never gained the knowledge of how to swim, even though the word "learn" isn't used. That said, it still sounds a little wonky even to the Spanish speaking ear.

Just to clarify, the example attached to this page is not the "past preterite" but the Present Perfect (or in Spanish, the pretérito perfecto compuesto).

This does not imply that an action has been "singularly begun and completed at a time in the past," as does the preterit.

Rather, in both languages, PP is used to address things that started in the past and which continue or repeat into the present.

So though I [learned/found out/acquired the knowledge] to drive a car at the age of 10, some sixty (+) years ago, since that time, I have known how to drive a car, and in the present, I still do.

That's accepted and probably the best English translation possible. It's worth noting, however, that translating this back into Spanish would give you: Ellas no han aprendido a nadar.

Or, if "saber" were being used: Ellas no saben nadar. This would give us literally "They don't know how to swim" but also, assuming they haven't forgotten, "They haven't learned how to swim."

The upshot is that with "saber" the present perfect would be redundant unless you explicitly wanted to say "They have not known how to swim". It's just as weird in Spanish as it is in English, and DL should scrap this sentence all together.

In English this translation doesn't make sense because it is not correct to use the present perfect here (reference: http://www.englishpage.com/verbpage/presentperfect.html).

Maybe it should be translated as "they didn't know how to swim" (past simple). If this is the case I don't understand why the present perfect can be used here in Spanish, or why it is used instead of the past simple.

Perhaps instead in should be translated as "they haven't learned how to swim" but I can't find any reference to "saber" being translated as "learn".

If someone could explain this to me it would be much appreciated.

1/29/2014, 5:25:33 PM

https://www.duolingo.com/zeunysos

In casual conversation in English, if we aren't going take the time to select our tenses carefully with regard to aspect and vantage, we tend to default to the preterite (past simple) when talking about the past. Spanish instead tends to default to their equivalent of what we call present perfect.

It's really just a matter of convention. So changing such constructions to past simple is probably the best way to translate them into English.

Could you please quote how the reference you link says it is "not correct" to use the present perfect here?

And how would you be avoiding the present perfect by saying "have not learned' instead of "have not known"?

Again, do a Google search for the exact phrase "have not known," and it will return something like 278,000,000 hits. That's 278 million. Admittedly, a number of those references are to "known" in one Biblical sense or another, but not nearly all of them.

Apparently, a lot of people have not known the phrase makes no sense.

1/29/2014, 7:02:19 PM

https://www.duolingo.com/raphi_rossa

If you google "have not known" then the very first result that comes up explains why it is not correct in English (in this case). The majority of the other results are biblical quotes, which does not mean that it is correct in modern English. Also there are some times when using "have not known" is correct. For example "I haven't known you very long". However, with the duolingo sentence here it is not. Have a look at any grammar reference page about using the present perfect and check if that sentence complies with any of the uses.

Also if you google that exact phrase "they have not known how to swim" you will find no results whereas "they didn't know how to swim" has over 2 million. However, you can't use a google search to prove that a phrase is grammatically correct or not. Google "haven't got nothing" and it will also find over 140 million pages and for "haven't done nothing" over 500 million. Google "that will learn you" and you will find over four billion pages, but "that will teach you" finds only 700 million.

I don't have a problem with this sentence because the grammar is incorrect, as many duolingo sentences in English are, but rather because it is SO incorrect that I can not understand the tense of the sentence.

Know isn't generally used with the present perfect tense, because we don't know something up until the point we learn it and then we know it and will continue to know it (unless we forget). Therefore past simple is almost always used.

So is this sentence in the past - they hadn't known how to swim at some point in the past but they do know now? Or the present - they haven't yet learned (known?) how to swim?

1/31/2014, 8:42:00 AM

This makes sense coming from Paraguayan Spanish because saber + another verb can mean "Do you do this regularly / Are you comfortable doing this" more or less. "Sabes tomar cerveza?" was often asked, and they're not literally asking "Do you know how to drink beer?" but more asking if you usually do. So the original sentence to me means something like, "They haven't been accustomed to swimming."

Present perfect is up to and including the present for verbs of state like "know", "like", "hate" and "be". An action verb may happen once or more times in the past. So here we have an unchanged state to the present. we can just use present simple. That is why it is "clunky".

I did, however, come up with some Olde English from the King James version Bible that has some vague similarity to the suggested "correct" sentence - but which is also just as clearly incorrect in terms of modern grammatical English useage, as confirmed by parallel translations from recent years.

American King James Version (AKJV) //For my people is foolish, they have not known me; they are silly children, and they have none understanding://

World English Bible //"For my people are foolish, they don't know me. They are foolish children, and they have no understanding.//

I suggest that the developers responsible for that silly English translation "have not known" proper modern English.

Neither the King James Bible nor the works of Shakespeare are written in "Olde English.," which went out of use some 450 years earlier. They are set in Early Modern English.

From Wikipedia: Modern English (sometimes New English or NE[3] as opposed to Middle English and Old English) is the form of the English language spoken since the Great Vowel Shift in England, which began in the late 14th century and was completed in roughly 1550.

With some differences in vocabulary, texts from the early 17th century, such as the works of William Shakespeare and the King James Bible, are considered to be in Early Modern English.

If the use of the present perfect with the verb "to know" were "clearly incorrect in terms of modern grammatical English useage, {sic]" it would have been easy enough by now for someone to have provided a citation of some kind of authority as to that "fact."

Thus far, no one has done so, and citing a comparison between "parallel translations" confirms nothing as to the "correctness" of either .the AKJV or the World English Bible.

Yep. I think DL's grammatically strange sentences are often the result of literal translations being given instead of natural (sometimes idiosyncratic) English, and I think this is exactly what is happening here. While in English we can say "They know how to swim" and "They do not know how to swim" we would not be likely to say "They have not known how to swim." More naturally we change the verb to "learnt/learned" giving us "They have not learnt how to swim." In Spanish this verb change is not necessary. They can say "Saben nadar" and "No saben nadar" and "No han sabido nadar." So the Spanish sentence is fine, it is just DL's literal English translation that is odd. The more natural "They have not learnt how to swim" is better (and is an accepted alternative answer).

It is awkward, agreed. I think it would only be used with "until now" added to the end. Or perhaps in the case of an entire culture or subgroup who wasn't accustomed to swimming? Definitely a limited usage!

However, we would say "They have never known how to swim." That would be more common.

In some other situations, it has seemed to me that 'sabido' could have a meaning closer to 'learned'. So I translated it that way and DL accepted it. It sounds more grammatical in English. 'They have not learned how to swim'. Can any native Spanish speakers comment on whether that is a reasonable translation?

This is not correct english. The correct word is learned to swim. Aprendido nadar.

It would seem to make more since if it was "They have not BEEN known to swim". Does that change the tense?

There is no mistake here. If you think otherwise, please provide a link or authority that prohibits the use of the present perfect with the verb, "to know."

You may disagree all you like but it isn't a sentence that would be used in English (nor Spanish probably) so why it has been included must be open to debate.

It has been included because it is an entirely valid English construct that mirrors an entirely valid Spanish phraseology. .

But debate is good, so in the spirit of debate, I say again: please provide a link or grammatical authority that supports your claim that "it isn't a sentence that would be used in English."

So then, why do people routinely say things such as:

  • Do you know how to swim?
  • Do you know how to drive?
  • Do you know how to read Spanish?

Learning and knowing are not mutually exclusive. One results in the other. You know facts, but you must learn them before you know them, right? Learning is both the process of acquiring knowledge (in and of itself, i.e, "facts") and also that of acquiring knowledge which is then applied to the development of a skill.

You cannot have the skills of, say, programming a computer, flying an airplane or doing brain surgery without first learning how and then knowing how to do them.

Does it really matter if it's an awkward English sentence? It isn't grammatically incorrect, it's just not the way we would say it. For me real question is, how would Spanish speakers phrase it and in what situation would they use this phrasing?

I doubt it. Without context it would be too narrow of a translation. "Ellas" could be females of any age, female animals, or any plural feminine noun. Likewise "ellos" with masculine options, and additionally for any unknown or mixed gender group.

That's not really the issue because you don't say "saber como nadar" in Spanish, you just say "saber hacer". The issue is that the use of the perfect tense sounds bizarre in English, and presumably in Spanish too, without a further context. It would make more sense, as Pecka suggested, if there was some sort of time frame.
