I always hear this structure 'I don't care what they say', can you please tell me why the people say this omit 'of- about' after 'care'?
I don't care what they say.
I don't care of/ about what they say.
What is the difference?
Care about something.
Care can be followed by a question word like:
I don't care what she does.
I don't care where he goes.
I don't care how much it costs.
However, I've also seen "I care about what's happening here".
In all these case the meaning is "you think something is important and you're interested in it. In negative ones it shows you're not interested in it ans it's not important.
