... top-level game; match being free of cheating (4)
I believe the answer is:
face
I believe this is a sextuple definition!!!
'top' is the first definition.
(thesaurus)
'level game' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'match' is the third definition.
(thesaurus)
'being' is the fourth definition.
(face is a kind of being)
'free' is the fifth definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'of' acts as a link.
'cheating' is the sixth definition.
(thesaurus)
Can you help me to learn more?
(Other definitions for face that I've seen before include "TV show" , "Surface; visage" , "set of features" , "Countenance, visage" , "'Cheeks, mouth, eyes etc (4)'" .)
