Golf peg found by child with man, abstinent (8)
I believe the answer is:
teetotal
'abstinent' is the definition.
(synonyms)
'golf peg found by child with man' is the wordplay.
'golf peg' becomes 'tee' (I've seen this before).
'found by' says to put letters next to each other.
'child' becomes 'tot' (term for a young child).
'with' is a charade indicator (letters next to each other).
'man' becomes 'Al' (man's name).
'tee'+'tot'+'al'='TEETOTAL'
(Other definitions for teetotal that I've seen before include "Sworn off alcohol" , "Completely abstaining from alcoholic drink" , "Not touching a drop" , "drunk? No way" , "Abstaining completely from alcoholic drinks" .)
