Given a yes-no question such as:
Did you call him?
Is it idiomatic to simply answer:
Yes. / No.
As opposed to:
Yes, I did. / No, I didn't.
or just:
I did. / I didn't.
I've noticed that in some languages simply answering yes or no seems to be the common unmarked way of answering (e.g. Spanish), but not in others (e.g. Portuguese).
Best Answer
Yes.
just on its own can sound very abrupt. I would not use it like that with a superior or client. To answer with one word and not continue the conversation is awkward. It's not really the yes on its own, but rather the silence afterwards.Yes, blah blah details blah
would be more normal.To a client or superior, I would say
Yes, I did.
if I had no more detail to give.To a peer, or in an informal context, I would say
yup
orja
, both accepted variations on yes for my area.
