Gave some ideas to an officer (5)
I believe the answer is:
dealt
'gave' is the definition.
(dealing is a kind of giving)
'some ideas to an officer' is the wordplay.
'some' means to look at the middle letters.
'to an officer' becomes 'lt' (abbreviation for lieutenant).
The middle letters of 'ideas' are 'dea'.
'dea'+'lt'='DEALT'
(Other definitions for dealt that I've seen before include "Traded" , "Dispensed (cards)" , "Delivered" , "Delta (anag.)" , "Doled out" .)
