Hi Babypink,
When a person says “technically” before their answer, it shows that they are answering the question factually, but they are not answering the real meaning of the question.
For your example… “single” and “married” are opposites. You are either one or the other. If a person asks “Are you single?” the factual question is “are you single or married?” but the real meaning of the question is “are you available for me to date you?” So the answer “technically, I am single” means that I am not married, but there are things that would make me unavailable to date you. I may already have a boyfriend but we’re not married yet or I may be a lesbian and not interested in dating a man, or my husband might have died and I’m single again but not interested in starting over, etc.
-- “Did they offer you the job?”
-- “Technically, no. But they said I should look for a letter from them on Monday.” (This suggests they will offer the job on Monday, but they haven’t offered it yet.)
-- “This house is expensive. Do you have money in the bank for it?”
-- “Technically, no. But I could sell some stocks.” (The money is not in the bank, but I do have money somewhere else, like in investments.)
-- “What a cute photo. Is that your daughter?”
-- “Technically, yes, but I gave her up for adoption right after the photo was taken” (She is biologically my daughter, but I am not the mother who raised her.)
