Decorations are or are not different (6)
I believe the answer is:
ornate
'decorations are' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs sometimes define each other.
'are not different' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'are'+'not'='arenot'
'arenot' is an anagram of 'ORNATE'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for ornate that I've seen before include "Over-elaborate" , "Much-decorated" , "Excessively decorated" , "Rich in decorative detail" , "Over-decorated" .)
