Soak back of suede on dry hide (7)
I believe the answer is:
secrete
'hide' is the definition.
(I know that secrete is a kind of hide)
'soak back of suede on dry' is the wordplay.
'soak' becomes 'ret' (ret can mean to soak in water).
'back of' says to take the final letters.
'on' means one lot of letters go next to another.
'dry' becomes 'sec' (similar in meaning).
The final letter of 'suede' is 'e'.
'ret'+'e'='rete'
'rete' put after 'sec' is 'SECRETE'.
(Other definitions for secrete that I've seen before include "Hide; as gland does" , "(Of gland) produce (a substance)" , "Hide - discharge" , "Hide away" , "Form substance for use within body, as liver does bile" .)
