Girl eager to provide cloth (7)
I believe the answer is:
nankeen
'cloth' is the definition.
(nankeen is a kind of cloth)
'girl eager' is the wordplay.
'girl' becomes 'nan'.
'eager' becomes 'keen' (I've seen this before).
'nan'+'keen'='NANKEEN'
'to provide' is the link.
(Other definitions for nankeen that I've seen before include "hard-wearing stuff" , "Chinese cotton cloth" , "Yellowish cotton cloth" , "mustard colour" , "Buff colour(ed cloth)" .)
