Comes round and gives in (7)
I believe the answer is:
relents
This clue is a double definition.
'comes round' is the first definition.
(I've seen this before)
'gives in' is the second definition.
(I've seen this in another clue)
'and' acts as a link.
(Other definitions for relents that I've seen before include "Gives way" , "Eases off" , "Becomes less severe and more lenient" , "is slackening" , "Shows mercy" .)
