Bath for one boy not in total agreement (3)
I believe the answer is:
uni
'bath' is the definition.
Both the answer and definition are singular nouns.
Maybe there's a link between them I don't understand?
'one boy not in total agreement' is the wordplay.
'one boy' becomes 'Ty'.
'not in' suggests deleting specific letters.
'total agreement' becomes 'unity' (I've seen this in another clue).
'unity' with 'ty' removed is 'UNI'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for uni that I've seen before include "Place of higher education (abbr)" , "University (abbreviation)" , "Seat of learning" , "Number of colleges" , "Queen's, Belfast, for example" .)
