Many not able to provide a word of opposite meaning (7)
I believe the answer is:
antonym
'a word of opposite meaning' is the definition.
(I've seen this before)
'many not able to' is the wordplay.
'many not' can be anagrammed to 'ANTONYM'.
However, I'm not clear how the anagram is indicated.
'provide' acts as a link.
Can you help me to learn more?
(Other definitions for antonym that I've seen before include "For villain, hero is one" , "opposing term" , "A word opposite in meaning to another" , "that means reverse" , "something completely different" .)
