Member starts with three old examples (3)
I believe the answer is:
Here is my best explanation:
'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 "A digit", "Lower digit", "End of foot", "Digit on foot", "One's nailed", "compliantly put on line", "front", "Kick", "Lower tip of something" and "Digit; kick".)
