After hours, did get around and opened up (7)
I believe the answer is:
dilated
'opened up' is the definition.
(I've seen this before)
'after hours did get around' is the wordplay.
I cannot really understand how this works, but
'after hours' could be 'late' (I've seen this in other clues) and 'late' is found in the answer.
The remaining letters 'did' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for dilated that I've seen before include "Became more open" , "Made more open/wide" , "like pupils in the dark" , "Made more open" , "Opened up" .)
