Head of company with talent to charge a great deal (8)
I believe the answer is:
cartload
'a great deal' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'head of company with talent to charge' is the wordplay.
'head of' indicates taking the first letters.
'with' is a charade indicator (letters next to each other).
'talent' becomes 'art' (I've seen this in another clue).
'to charge' becomes 'load' (loading is a kind of charging).
The initial letter of 'company' is 'c'.
'c'+'art'+'load'='CARTLOAD'
Can you help me to learn more?
(Other definitions for cartload that I've seen before include "Enough for a horse to pull" , "large quantity in vehicle" .)
