Had a row about the fifty one had drawn from the bank (7)
I believe the answer is:
clashed
'had' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'a row about the fifty one had drawn from the bank' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'about' could be 'c' (abbreviation for 'circa') and 'c' is found within the answer.
'fifty' could be 'l' (Roman numeral) and 'l' is found within the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'one had' could be 'd' (I've seen this in other clues) and 'd' is present in the answer.
The remaining letters 'sh' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for clashed that I've seen before include "Came into conflict" , "Was incompatible" .)
