Prudence seeing dodgy gift horse (9)
I believe the answer is:
foresight
'prudence' is the definition.
(foresight is a kind of prudence)
'dodgy gift horse' is the wordplay.
'dodgy' is an anagram indicator.
'gift'+'horse'='gifthorse'
'gifthorse' anagrammed gives 'FORESIGHT'.
'seeing' acts as a link.
(Other definitions for foresight that I've seen before include "Planning" , "Caution" , "Ability to anticipate" , "Clairvoyance" , "Prescience" .)
