Getting used to ruining production (7)
I believe the answer is:
inuring
'getting' is the definition.
The definition and answer can be both related to change as well as being present participle verbs.
Perhaps there's a link between them I don't understand?
'to ruining production' is the wordplay.
'production' indicates an anagram.
'ruining' is an anagram of 'INURING'.
'used' acts as a link.
Can you help me to learn more?
(Other definitions for inuring that I've seen before include "Ruining (anag.)" , "Hardening" .)
