Good member of family, though lean and scraggy (5)
I believe the answer is:
gaunt
'scraggy' is the definition.
(thesaurus)
'good member of family' is the wordplay.
'good' becomes 'g' (abbreviation).
'member of family' becomes 'aunt' (I've seen this before).
'g'+'aunt'='GAUNT'
'though lean and' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for gaunt that I've seen before include "Very thin, cadaverous" , "Lean and haggard" , "Thin or emaciated" , "place associated with Edward III's son" , "Hence John" .)
