Sort of mirror on small badge cut off (8)
I believe the answer is:
resemble
'sort of mirror' is the definition.
'on small badge cut off' is the wordplay.
'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'.
're'+'s'+'emble'='RESEMBLE'
(Other definitions for resemble that I've seen before include "Be like another in appearance" , "Have a similar appearance to (another)" , "be like or similar to" , "Appear like another person" , "Appear similar to" .)
