Join woman on Times (5)
I believe the answer is:
annex
'join' is the definition.
(I've seen this before)
'woman on times' is the wordplay.
'woman' becomes 'anne' (I've seen this before**).
'on' means one lot of letters go next to another.
'times' becomes 'x' (multiplication sign).
'anne'+'x'='ANNEX'
(Other definitions for annex that I've seen before include "Add to the end; take possession of" , "Take (land) by conquest" , "Attach after conquest" , "Attach (land)" , "Addition to a document" .)
