Notice a payment to tailor (5)
I believe the answer is:
adapt
'to tailor' is the definition.
(I've seen this in another clue)
'notice a payment' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'payment' becomes 'pt' (I can't justify this - if you can you should believe this answer much more).
'ad'+'a'+'pt'='ADAPT'
Can you help me to learn more?
(Other definitions for adapt that I've seen before include "Adjust (to changes)" , "Adjust (to new condition)" , "Accommodate" , "Become adjusted to new conditions" , "Tailor" .)
