Live somewhere in Herts, but with caution (6)
I believe the answer is:
beware
'herts but with caution' is the definition.
I can't tell whether this defines the answer.
'live somewhere' is the wordplay.
'live' becomes 'be' (synonyms).
'somewhere' becomes 'ware' (I am not sure about this - if you are sure you should believe this answer much more).
'be'+'ware'='BEWARE'
'in' is the link.
Can you help me to learn more?
(Other definitions for beware that I've seen before include "Archaic warning to be careful, danger ahead" , "Archaic warning to watch out, danger ahead" , "Wee bra (anag)" , "Be cautious about" , "Archaic injunction to be careful, look out" .)
