Some associates I met inside, return to catalogue individual pieces (7)
I believe the answer is:
itemise
'catalogue individual pieces' is the definition.
'itemise' can be an answer for 'catalogue' (both can mean to make a list). I'm unsure of the 'individual pieces' bit.
'some associates i met inside return' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'return' shows that the letters should be reversed in order.
'esimeti' is hidden in the letters of 'associates i met inside'.
'esimeti' back-to-front is 'ITEMISE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for itemise that I've seen before include "Set down separately" , "List each thing separately" , "make inventory" , "Make a list" , "Formulate a list" .)
