Lowering a can into crumpled bag (7)
I believe the answer is:
abating
'lowering' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I don't see?
'a can into crumpled bag' is the wordplay.
'can' becomes 'tin' (synonyms).
'into' means one lot of letters goes inside another.
'crumpled' indicates anagramming the letters.
'a'+'tin'='atin'
'bag' with letters rearranged gives 'abg'.
'atin' going within 'abg' is 'ABATING'.
Can you help me to learn more?
(Other definitions for abating that I've seen before include "Subsiding" , "on the decline" , "Becoming less intense" , "Getting less" , "Slacking off, dyeing away" .)
