On taking first wife out, gulp down pasty (6)
I believe the answer is:
sallow
'pasty' is the definition.
(I've seen this before)
'on taking first wife out gulp down' is the wordplay.
I cannot really see how this works, but
'first' could be 'low' (synonyms) and 'low' is found within the answer.
The remaining letters 'sal' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sallow that I've seen before include "Pale; sickly" , "Pale-looking - tree ..." , "(Of complexion) rather yellowish" , "Unhealthily pale; a willow" , "Pale or yellowish colour" .)
