GBS left something warm (5)
I believe the answer is:
'something warm' is the definition.
I can't judge whether this definition defines the answer.
'gbs left' is the wordplay.
'gbs' becomes 'shaw' (I've seen this in another clue).
'left' becomes 'l' (common abbreviation).
Can you help me to learn more?
(Other definitions for shawl that I've seen before include "Wrap for a baby" , "Cover for head and shoulders" , "Loose garment for head or shoulders" , "Baby wrapper" , "Female garment" .)
