Couple and haul, moving weight forwards (3)
I believe the answer is:
two
'couple' is the definition.
(two people or things)
'haul moving weight forwards' is the wordplay.
I cannot really understand how this works, but
'weight' could be 'w' (short for weight) and 'w' is present in the answer.
The remaining letters 'to' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for two that I've seen before include "A pair (3)" , "Pair, deuce" , "not very many" , "Number in company, some say" , "Couple, brace" .)
