Vet again checks animal that's caught cold (9)
I believe the answer is:
reinspect
'animal that's caught cold' is the definition.
I can't judge whether this definition defines the answer.
'vet again' is the wordplay.
I cannot really see how this works, but
'vet' could be 'inspect' (inspect can mean to vet or check) and 'inspect' is located in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'checks' is the link.
Can you help me to learn more?
(Other definitions for reinspect that I've seen before include "Further check" , "Do follow-up work for Ofsted" .)
