Flyer sees V1 in two areas by hill (7)
I believe the answer is:
aviator
'flyer' is the definition.
(I know that aviator is a type of flyer)
'v1 in two areas by hill' is the wordplay.
'vv' becomes 'vi' (I can't justify this - if you can you should believe this answer much more).
'in' means one lot of letters goes inside another.
'two areas' becomes 'AA' (mathematical abbreviation for 'area' written twice).
'by' says to put letters next to each other.
'hill' becomes 'tor' (tor is a kind of hill).
'vi' inserted into 'aa' is 'avia'.
'avia'+'tor'='AVIATOR'
'sees' is the link.
Can you help me to learn more?
(Other definitions for aviator that I've seen before include "Aeronaut" , "Pilot of plane" , "Airman" , "Woman in a flying machine" , "He travels up" .)
