A financial transaction, we hear, that's not with others (5)
I believe the answer is:
alone
'not with others' is the definition.
I can't tell whether this definition defines the answer.
'a financial transaction we hear' is the wordplay.
'financial transaction' becomes 'loan' (I've seen this in another clue).
'we hear' indicates a 'sounds like' (homophone) clue.
'loan' sounds like 'lone'.
'a'+'lone'='ALONE'
'that's' is the link.
Can you help me to learn more?
(Other definitions for alone that I've seen before include "Note of charges" , "On one's own" , "unique" , "Exclusively, by oneself" , "Unaccompanied" .)
