Does anyone know why the phrase 'make time for' uses a zero article for time? I know time is uncountable and most phrases about time use a zero article (spend time, save time, etc), however if the time is specific (you're wasting the time I gave you) it can have 'the.' So why in the phrase 'I'll make time for you at 7' is there no definite article?
Time is still uncountable here. It's like saying you'll make room for something. To "make time for" someone or something is to free up time, to make oneself available. That doesn't change just because it's happening at a specific time.
