Make irregular edges in rococo semi when restored (9)
I believe the answer is:
randomise
'restored' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'make irregular edges in rococo semi' is the wordplay.
I cannot really understand how this works, but
'make' could be 'do' (doing is a kind of making) and 'do' is located in the answer.
an anagram of 'semi' is 'mise' which is within the answer.
The remaining letters 'ran' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'when' is the link.
Can you help me to learn more?
(Other definitions for randomise that I've seen before include "Haphazardly set up" , "Mix up" , "Scrap order" , "Destroy order of" , "set up unsystematically" .)
