Something stuffed in woman's underwear (5)
I believe the answer is:
teddy
'underwear' is the definition.
(all-in-one undergarment)
'something stuffed in woman's' is the wordplay.
I cannot quite understand how this works, but
'woman' could be 'eddy' and 'eddy' is found in the answer.
A single letter 't' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for teddy that I've seen before include "Stuffed bear" , "plaything" , "Child's soft toy" , "Stuffed toy" , "A child's toy bear" .)
