Member starts with three old examples (3)
I believe the answer is:
toe
'member' is the definition.
(toe is a kind of member)
'starts with three old examples' is the wordplay.
'starts with' suggests taking the first letters.
The first letters of 'three old examples' is 'TOE'.
(Other definitions for toe that I've seen before include "End of sock" , "Digit on foot" , "low digit" , "'Little piggy'" , "Extremity of the body" .)
