Squeal at wrestling matches (6)
I believe the answer is:
equals
'matches' is the definition.
('equal' can be a synonym of 'match')
'squeal at wrestling' is the wordplay.
'squeal' can be anagrammed to 'EQUALS'.
However, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for equals that I've seen before include "Is as good as" , "Peers, matches" , "Is identical in quantity, value" , "Corresponds to" , "They're at the same level" .)
