One who flies from Swansea via Torquay (7)
I believe the answer is:
aviator
'one who flies' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'from swansea via torquay' is the wordplay.
'from' says the answer is hidden in the clue.
'AVIATOR' is hidden within 'swansea via torquay'.
Can you help me to learn more?
(Other definitions for aviator that I've seen before include "one in a crate?" , "Aircraft pilot" , "Ace, say," , "Pilot; style of sunglasses" , "One flying aircraft" .)
