Some cut is altogether peculiar to tailor (9)
I believe the answer is:
customise
'tailor' is the definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'some cut is altogether peculiar' is the wordplay.
'some cut is' can be anagrammed to 'CUSTOMISE'.
Though, I'm not sure how the anagram is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for customise that I've seen before include "Adapt for particular requirements" , "Make alterations" .)
