what does "come" exactly mean?
when I saw the phrasal verbs that we have with the word come I saw this:
come along: arrive at a place (Not many people bought tickets for the concert in advance, but quite a few came along and bought tickets at the door.)
come apart: separate into pieces (The antique picture frame just came apart in my hands.)
come round: become conscious again (A nurse was with me when I came round after the operation.)
come out: disappear or become less strong (Let your shirt soak overnight and the stain will probably come out.), become public knowledge after it has been kept secret (If this story comes out about the Prime Minister, he'll have to resign.), be given to people (When do your exam results come out?), leave after a period in a place (Ava's coming out of hospital at the weekend. She's much better now.)
come off: happen successfully or as planned (I was planning to arrange a surprise holiday for her birthday, but I'm not sure it's going to come off.)
came about: happened, especially something which is not planned (I've had to organise the school fair again this year - I'm not quite sure how that came about.)
comes up, came across, come up against, come to, come down to.
