Beaming artist with woman worker (7)
I believe the answer is:
radiant
'beaming' is the definition.
(synonyms)
'artist with woman worker' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'with' means one lot of letters go next to another.
'woman' becomes 'Di' (short for Diana).
'worker' becomes 'ant' (worker is a type of ant).
'ra'+'di'+'ant'='RADIANT'
(Other definitions for radiant that I've seen before include "Lit up" , "glowing with happiness" , "Resplendent" , "Shining - happy" , "with good humour" .)
