Grandma eager to find a hard-wearing fabric (7)
I believe the answer is:
nankeen
'a hard-wearing fabric' is the definition.
'nankeen' can be an answer for 'fabric' (nankeen is a kind of fabric). I am not sure about the 'a hard-wearing' bit.
'grandma eager' is the wordplay.
'grandma' becomes 'nan' (I've seen this before).
'eager' becomes 'keen' (I've seen this before).
'nan'+'keen'='NANKEEN'
'to find' acts as a link.
Can you help me to learn more?
(Other definitions for nankeen that I've seen before include "Yellowish stuff" , "hard-wearing stuff" , "Chinese cotton cloth" , "Durable yellow cotton fabric, originally from China" , "trouser material" .)
