Well, yes- I agree that some of the genitive noun phrases in the course are awkward, but I find them useful as demonstrations of this particular grammatical point (and their awkwardness forces the learner to analyze them more for their structure and not their meaning). Anyway, I appreciate your answer- Ευχαριστώ!
Yes, but it would be wrong to give anyone the impression that 'the salt of the salad' is English or would have any clear meaning to an English speaker. It is interesting that Greek sees a dish or food as possessing its ingredients or accompaniment while English says they are "in" or contained by or come with the dish. So the famous notice on food packets in England "This product contains nuts' where Greek would definitely use έχει. I have persuaded Duo to allow 'The hamburger comes with chips' instead of 'has chips'
For me 'the salt for the salad' or 'the salt in the salad' would be more natural. However a year ago you did say that this sentence is awkward in Greek as well as English so maybe your initial thought about lopping it was right! Some words like 'salad' just don't have much need for a genitive construction! I suppose it is used because our vocabulary is so limited at this stage but I think introducing new nouns in natural sentences would be more useful than trying to make sense out of unsatisfactory ones. But thank you for this brilliant free opportunity to learn Greek!
Perhaps the solution (not the saline solution:-) is to present the literal translation followed by a possible free translation, such as:
Literally 'the salt of the salad' , or perhaps meaning 'the salad salt'.
NB 'perhaps', because as B Googe above says 'salad's salt is a bit obscure to an English speaker.
Every skill has a Tips & notes section with information, explanations of the grammar and vocabulary, etc relevant to that skill.
You can find it at the start of each lesson by clicking on the word "TIPS.
To find exactly which word/phrase is needed for each sentence all you need to do is pass your cursor over that word/phrase and a list of translations will drop down. There many be many but you should chose the top translation...Duo does that so you don't have to guess.
You should also look at the Greek Forum page full of other helpful links.
Scroll down and look at them. Open some of them such as:
Yes, these are rather difficult expressions to transpose...notice I don't even use translate...from one language to another. In particular English has rather fixed means of expressing certain things. There are other comments on this page with some suggestions. What we a trying to achieve is a correct Greek expression with an English one that as faithfully as possible represents that.
We put a good deal of research into these and hope they are helpful.
