After strike, seek men's submission (8)
I believe the answer is:
meekness
'submission' is the definition.
(I've seen this before)
'after strike seek men's' is the wordplay.
'after strike' is an anagram indicator (I've seen this in other clues).
'seek'+'mens'='seekmens'
'seekmens' anagrammed gives 'MEEKNESS'.
(Other definitions for meekness that I've seen before include "Submissive quality" , "Submissive nature" , "Submissive humility" , "Formally inform" , "Timidity" .)
