Would you say the word 'reciprocate' (in the context of responding to a courtesy/greeting question by returning the exact same question) is too formal a word to expect in casual conversations.
- If so what are some more informal alternatives? Does the phrase "ask back" work? As in:
When someone greets you with 'how are you?', you have to ask back.
- Conversely, I would also like to ask for some formal alternatives as well.
Many thanks in advance.
