Colleague, old woman initially embraced by beauty (2-6)
I believe the answer is:
co-worker
'colleague' is the definition.
(I've seen this before)
'old woman initially embraced by beauty' is the wordplay.
'initially' suggests taking the first letters.
'embraced by' indicates putting letters inside.
'beauty' becomes 'corker' (I've seen this before).
The initial letters of 'old woman' is 'ow'.
'ow' going inside 'corker' is 'CO-WORKER'.
(Other definitions for co-worker that I've seen before include "Colleague - associate" , "Fellow employee" .)
