Has two wheels and is used, with love, by a coster (7)
I believe the answer is:
scooter
'has two wheels and is used' is the definition.
I can't tell whether this definition defines the answer.
'love by a coster' is the wordplay.
I cannot quite understand how this works, but
'love' could be 'o' (love means zero in tennis) and 'o' is found within the answer.
an anagram of 'coster' is 'scoter' which is within the left over letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for scooter that I've seen before include "Wheeled board with steering handle" , "Vehicle and child's toy" , "Two-wheeled motor vehicle" , "To score (anag)" , "Child's two-wheeled vehicle" .)
