Face pressure in a group (6)
I believe the answer is:
aspect
'face' is the definition.
(thesaurus)
'pressure in a group' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'in' indicates putting letters inside.
'group' becomes 'sect' (I've seen this in other clues**).
'a'+'sect'='asect'
'p' put inside 'asect' is 'ASPECT'.
(Other definitions for aspect that I've seen before include "Viewpoint or view" , "The appearance presented" , "'View, perspective (6)'" , "Feature; appearance" , "Particular part or element, of a problem say" .)
