Trophy from a ceramics moulding held aloft (8,3)
I believe the answer is:
americas cup
'trophy' is the definition.
(I've seen this before)
'a ceramics moulding held aloft' is the wordplay.
'moulding' indicates an anagram.
'held aloft' becomes 'up' (I can't justify this - if you can you should believe this answer much more).
'ceramics' with letters rearranged gives 'mericasc'.
'a'+'mericasc'+'up'='AMERICAS CUP'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for americas cup that I've seen before include "Yacht-racing trophy" , "main competition" , "sailors want to win it" , "Competition for boats" , "International match between two sailing yachts, first held in 1851" .)
