For some reason, using an apostrophe on a plural, such as dogs', is marked as a typo on the main page. However, once you click on discussion, there is the correct answer at the top, complete with the apostrophe that was just marked as a typo. Unfortunately, now that we are using the upgraded program we can no longer submit a correction. It's a problem with the program, not with us.
I don't know. I am an expert on apostrophes and so got them all right. Hence the risk of being penalised didn't arise. But if I were marking this, I would penalise given that a misplaced apostrophe could render a singular plural or vice versa, thus undermining this whole lesson.
Well, it's reassuring that you didn't spot any errors in our apostrophes! Please report them to us if you do.
We don't have any control, as far as I know, over what is accepted in terms of punctuation, accents etc. As it's supposed to be a game as well, the system tends to mark things like this correct and gives you an error message.
I'm not familiar with this end of things, though. Perhaps someone more knowledgeable can shed more light on this.
I hate to say it, but I've spotted a few cases of the apostrophe being in the wrong place but being marked as a typo and not as an error. I do know where my apostrophes go in English, but I'm never sure in the Irish, when it's genitive, whether it's singular or plural so I have sometimes translated things like "the dog's food" when it's supposed to be "the dogs' food." I don't know how many of these there are, but I do try to report them when I remember to.
Strong plurals are generally any plural that doesn't involve slenderization.
In the case of strong plurals, the genitive and nominative singulars are (usually) the same, as are the plurals. In weak plurals, which involve slenderization, the nominative plural is the same as the genitive singular and vice versa.
A lot of people struggle with what actually are 2 distinct problems. One problem is the foreign language, the other is grammar that wasn't taught for their own language. If you break the struggle down to these separate issues, you can focus on learning how grammatical cases work in English, before rising to the Irish challenge. I think this website is quite straightforward for understanding cases in English: https://www.learngrammar.net/english-grammar/case . Just note that they call the genitive case "possessive case" (and don't worry about it).
I think I will give up using the suggested "labels" and just choose to use the keyboard as so often the options do not add up to the correct answer! (It was only an apostrophe missing this time, and instead of dogs' I tried putting dogs's - since that was what was on offer - but it was not accepted. I suppose that's good, since it would not actually be correct!) :D
It depends on the declension type: "strong" nouns have the same plural form for both genitive and nominative, whereas "weak" nouns have a distinct genitive ending (which may or may not look the same as nominative singular).
The way a noun decline isn't obvious from it's nominative singular, so when learning a new word it might be useful to take a look at it's genitive and plural forms to see how it declines.
