… fellow lied about section's answers (6)
I believe the answer is:
fields
'answers' is the definition.
(fielding is a kind of answering)
'fellow lied about section's' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'about' is an anagram indicator.
'section' becomes 's' (legal abbreviation).
'lied' is an anagram of 'ield'.
'f'+'ield'+'s'='FIELDS'
(Other definitions for fields that I've seen before include "See 5" , "Cleared areas of land" , "Enclosed piece of land" , "Cleared tracts of land" , "See 25 Down" .)
