They take heavy loads from different yards (5)
I believe the answer is:
drays
'they take heavy loads' is the definition.
The definition suggests an adverb but the answer is not.
'different yards' is the wordplay.
'different' indicates anagramming the letters.
'yards' anagrammed gives 'DRAYS'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for drays that I've seen before include "Delivery carts without sides" , "Beer wagons" .)
