Looked for gold, perhaps, around mid-September (5)
I believe the answer is:
ogled
'looked' is the definition.
(ogling is a kind of looking)
'gold perhaps around mid-september' is the wordplay.
'perhaps' indicates an anagram.
'around' indicates putting letters inside.
'mid' says to take the centre (mid- can mean the middle of something).
'september' becomes 'sep' (short for September).
The middle letter of 'sep' is 'e'.
'gold' is an anagram of 'ogld'.
'ogld' going around 'e' is 'OGLED'.
'for' acts as a link.
(Other definitions for ogled that I've seen before include "Eyed lustily" , "Looked at lecherously" , "Eyed lustfully" , "Eyed lecherously" , "Looked flirtatiously at" .)
