Sort of mirror on small badge cut off (8)
I believe the answer is:
Here is my best explanation:
'sort of mirror' is the definition.
'on small badge cut off' is the subsidiary indication.
'on' becomes 're' ('on' can be mean 'with reference to'**).
'small' becomes 's' (abbreviation - e.g. clothes size).
'badge' becomes 'emblem' (I've seen this before).
'cut off' means to remove the last letter.
'emblem' with its final letter taken away is 'emble'.
(Other definitions for resemble that I've seen before include "Be like another in appearance", "Look similar to", "Mirror", "Appear like another person", "Look like (someone/something)", "Appear similar to", "Be similar to", "be like or similar to", "Have a similar appearance to (another)" and "Echo".)
