It seems that שמן is used for both 'fat' and 'oil' however I believe the exact word for oil to be 'נפט' but then again, oil could eventually be just 'בנזין' as well...
Having several words for the same things draws us into the differences of exact words range of meanings that might vary from a language to another...
It's pretty hard for me to tell when 'נפט' is appropriate and when it's not.
Anyone cares to enlighten me on the matter :) ?
I'm rather usually angry at Duolingo to validate with mistakes counted as typo. I mean failing doesn't do you much wrong in the end.
However being granted with success when you make mistakes just settle you for long-term issues with the language.
As a matter of personal taste, I'd rather fail for every typo.
I reckon that you just need to check what typo you eventually did...
However, you might just sometime overlook it as a success with typos and a plain success are visually quite similar.
I believe it would be better if you'd get some in between color when you have typos, like dunno כתום for success with typos maybe :) ?
On the other hand, sometimes I feel like some sentence/structure could be correct but that these particular cases are just not integrated into Duolingo.
And in this second case I indeed feel the other way around as I don't know if I failed because I missed something or if it's actually Duolingo that missed...
For instance here I failed with "I have no fat, sorry." With in mind something around the idea of "I can't eat fat" or the like.
This might be incorrect for a bunch of reasons, not being a native English speaker doesn't help either. But as I've seen a bunch of case where Duolingo misses valid answers I can't tell where I stand when this happens and it's a bit annoying.
