Warrior’s belt is smooth, most ornate (7)
I believe the answer is:
baldric
'warrior's belt' is the definition.
'baldric' can be an answer for 'belt' (baldric is a kind of belt). I am not certain of the 'warrior's' bit.
'smooth most ornate' is the wordplay.
'smooth' becomes 'bald' (I've seen this in other clues).
'most ornate' becomes 'ric' (I can't explain this - if you can you should believe this answer much more).
'bald'+'ric'='BALDRIC'
'is' is the link.
Can you help me to learn more?
(Other definitions for baldric that I've seen before include "Strapping swordsman carried" , "Carrier for weapon" , "Sword belt" , "Sword-belt" , "Edmund's servant" .)
