turn up: meaning and explanation
The phrasal verb to turn up is used to say that someone or something arrived or appeared unexpectedly.
Imagine you’re getting married, and one of your relatives comes to the wedding without being invited. You would say that they turned up.
If we use this phrasal verb in the negative (e.g. my friend didn’t turn up) then it has the opposite meaning – we were expecting someone, and they didn’t come. Imagine you’re late for work because you were waiting for a bus which didn’t arrive when you expected it to. You would tell your boss that the bus didn’t turn up on time.
