Mirror put back together again without any silvering initially (8)
I believe the answer is:
resemble
'mirror' is the definition.
(mirror can mean to resemble or look like)
'back together again without any silvering initially' is the wordplay.
I cannot really see how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is found in the answer.
The remaining letters 'semble' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'put' is the link.
Can you help me to learn more?
(Other definitions for resemble that I've seen before include "Look like (someone/something)" , "Appear like another person" , "Have similarities to" , "Look similar to" , "Have a similar appearance to (another)" .)
