Field officer referring to boss’s facial feature (8)
I believe the answer is:
forehead
'facial feature' is the definition.
'forehead' can be an answer for 'feature' (forehead is a kind of feature). I am not certain of the 'facial' bit.
'field officer referring to boss's' is the wordplay.
'field officer' becomes 'fo' (this might be a standard abbreviation of which I'm unaware).
'referring to' becomes 're' ('re' means regarding or about).
'boss' becomes 'head' (synonyms).
'fo'+'re'+'head'='FOREHEAD'
Can you help me to learn more?
(Other definitions for forehead that I've seen before include "Space above the eyes" , "Upper part of the face" , "Front of the head" , "Brow" , "Frontal bone" .)
