Woven fabric wife introduced to farm (5)
I believe the answer is:
twill
'woven fabric' is the definition.
(I've seen this before)
'wife introduced to farm' is the wordplay.
'wife' becomes 'w' (abbreviation).
'introduced to' is an insertion indicator.
'farm' becomes 'till' (to till is to work on land).
'w' put inside 'till' is 'TWILL'.
(Other definitions for twill that I've seen before include "Diagonal-weave fabric" , "Strong woven fabric" , "Fabric woven to produce a surface of diagonal parallel ridges" , "Material" , "Fabric weave with parallel diagonal lines" .)
