For transport, one may get the sorrel out (7)
I believe the answer is:
lorries
'for transport one may get the sorrel out' is the definition.
I can't tell whether this definition defines the answer.
'one may get the sorrel out' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
an anagram of 'sorrel' is 'lorres' which is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lorries that I've seen before include "Vehicles for transporting goods" , "Large motor vehicles for carrying heavy goods" , "Large transport vehicles" , "Truck with no sides" , "forms of transport" .)
