Our group adds wrinkles to ways of working (6)
I believe the answer is:
usages
'ways of working' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps you can see a link between them that I can't see?
'our group adds wrinkles' is the wordplay.
'our group' becomes 'us'.
'adds wrinkles' becomes 'ages' (I can't explain this - if you can you should believe this answer much more).
'us'+'ages'='USAGES'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for usages that I've seen before include "speech patterns" , "Habitual or customary practices" , "Linguistic norms" , "Customary treatments, practices" , "Customs." .)
