Draw a portrait of a member, we hear (4)
I believe the answer is:
limn
'draw a portrait' is the definition.
'limn' can be an answer for 'draw' (limning is a kind of drawing). I'm not certain of the 'a portrait' bit.
'a member we hear' is the wordplay.
'a member' becomes 'limb' (member can mean a limb).
'we hear' indicates a 'sounds like' (homophone) clue.
'limb' sounds like 'LIMN'.
'of' is the link.
Can you help me to learn more?
(Other definitions for limn that I've seen before include "Represent in painting" , "Depict or describe" , "Paint or draw, or portray in words" , "Paint or Illuminate" , "Paint or describe in words" .)
