Even Dad's starting to recede (3)
I believe the answer is:
par
'even' is the definition.
(I've seen this in other clues)
'dad's starting to recede' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'starting to' indicates taking the first letters.
The first letter of 'recede' is 'r'.
'pa'+'r'='PAR'
(Other definitions for par that I've seen before include "Normal golfing score" , "standard for a pro" , "level footing" , "Average or even, as for the course" , "Rating of strokes required for hole (golf)" .)
