Ring the woman in strife (6)
I believe the answer is:
washer
'ring' is the definition.
(thesaurus)
'the woman in strife' is the wordplay.
'the woman' becomes 'she' (I've seen this before).
'in' means one lot of letters goes inside another.
'strife' becomes 'war' (I've seen this before).
'she' placed inside 'war' is 'WASHER'.
(Other definitions for washer that I've seen before include "Seal to prevent leakage" , "Rendered sightless" , "keep things firm" , "Rubber ring securing joint" , "Plumber often wants it" .)
