Usyk say needs minute stopping man (5)
I believe the answer is:
champ
'usyk say' is the definition.
I can't tell whether this definition defines the answer.
'minute stopping man' is the wordplay.
'minute' becomes 'm' (abbreviation).
'stopping' indicates putting letters inside (inserted letters stop or plug a gap).
'man' becomes 'chap' (term for a man).
'm' going into 'chap' is 'CHAMP'.
'needs' acts as a link.
Can you help me to learn more?
(Other definitions for champ that I've seen before include "Show impatience" , "boxer who is top dog?" , "Title holder (abbr)" , "Masticate, gnaw" , "Munch noisily; winner" .)
