Soon introduce leathery extremities (9)
I believe the answer is:
presently
'soon' is the definition.
(I know that soon can be written as presently)
'introduce leathery extremities' is the wordplay.
'introduce' becomes 'present' (presenting is a kind of introducing).
'leathery extremities' becomes 'ly' (I can't justify this - if you can you should believe this answer much more).
'present'+'ly'='PRESENTLY'
Can you help me to learn more?
(Other definitions for presently that I've seen before include "Soon, in a little while" , "In the near future" , "Before long" , "At the moment" .)
