Join woman with a kiss (5)
I believe the answer is:
annex
'join' is the definition.
(I've seen this before)
'woman with a kiss' is the wordplay.
'woman' becomes 'anne' (I've seen this before**).
'with' means one lot of letters go next to another.
'a kiss' becomes 'x'.
'anne'+'x'='ANNEX'
(Other definitions for annex that I've seen before include "Addition to a document" , "Add by conquest or occupation" , "Appropriate" , "Take by force" , "Add to one's territory" .)
