Ornamental band on wall could turn to ice, we hear (6)
I believe the answer is:
frieze
'ornamental band' is the definition.
(I've seen this before)
'ice we hear' is the wordplay.
'ice' becomes 'freeze' (I've seen this before).
'we hear' indicates a 'sounds like' (homophone) clue.
'freeze' is a homophone of 'FRIEZE'.
'on wall could turn to' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for frieze that I've seen before include "Part of temple wall" , "Decorative horizontal band" , "Rough, heavy cloth or decorative wall band" , "Very greedy eater" , "Decorator's band" .)
