Agree three letters with number inside for reading out (3,3,2,3)
I believe the answer is:
see eye to eye
'agree' is the definition.
(seeing eye to eye is a kind of agreeing)
'three letters with number inside for reading out' is the wordplay.
I cannot quite see how this works, but
'number' could be 'e' (e is a kind of number) and 'e' is present in the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for see eye to eye that I've seen before include "Think alike" , "Concur; in accord" , "Agree with someone" , "Speak the same lingo" .)
