Foreign Office ambassador goes in to study area between temples (8)
I believe the answer is:
forehead
'area between temples' is the definition.
I can't tell whether this defines the answer.
'foreign office ambassador goes in to study' is the wordplay.
'foreign office' becomes 'FO' (abbreviation).
'ambassador' becomes 'he' (His or Her Excellency).
'goes in' is an insertion indicator.
'to study' becomes 'read' (synonyms).
'he' going inside 'read' is 'rehead'.
'fo'+'rehead'='FOREHEAD'
Can you help me to learn more?
(Other definitions for forehead that I've seen before include "Space above the eyes" , "Front of the head" , "Brow" , "Frontal bone" , "Upper part of the face" .)
