Knowing a place in Herts (5)
I believe the answer is:
aware
'knowing' is the definition.
(I've seen this before)
'a place in herts' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
The remaining letters 'ware' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aware that I've seen before include "fly" , "Knowing (of something)" , "Conscious or having knowledge of" , "Having knowledge of, informed" , "Alert, conscious of" .)
