Woman: one taking bow? (5)
I believe the answer is:
viola
'bow?' is the definition.
(thesaurus)
'woman one' is the wordplay.
'woman' becomes 'viol' (I can't explain this - if you can you should believe this answer much more).
'one' becomes 'a' (a thing is one thing).
'viol'+'a'='VIOLA'
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for viola that I've seen before include "Sebastian's sister" , "Bloomer" , "Instrument slightly larger than violin and of lower pitch" , "String quartet member" , "Sebastian's twin (Twelfth Night)" .)
