Plus, I think there it would make sense to have an/a in/definite article if not plural.
I've been told "Be careful not to confuse "handy" and "useful"!" in my answer, but I'm not a native English speaker and I don't really see the difference between the two. Anyone can exlpain?
I would say that handy is more informal and might imply being convenient more than the word "useful" does if I had to note a difference in meaning. It's definitely less formal though.
Also, a person can be considered "handy" if they're good at fixing things, but you wouldn't necessarily say they're "useful" (not that they aren't! It's just that in that case, it's almost like saying "skilled")
Handy would refer more in the current situation or context of what is going on while useful can mean that it's applicable and adaptable or have much help/ Useful can mean handy but handy doesn't necessarily mean useful
I'm pretty sure that they are exact synonyms. It is probably only that one of 'handy' or 'useful' (the one you got wrong) is not programmed as a correct answer, rather than it being wrong!
I’m guessing that 'Computer' is actually a loan word from English. My question is why hasn’t the first letter 'c' been changed to a 'k' for use in German, as one would expect?
