Season for a trip in America? (4)
I believe the answer is:
fall
This clue might be a double definition.
'season' is the first definition.
(alternative name for autumn)
'trip in america?' is the second definition.
'fall' can be an answer for 'trip' (fall is a kind of trip). I am not certain of the 'in america?' bit.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for fall that I've seen before include "A season in Vermont?" , "Tumble, drop" , "Autumn; plummet" , "What Americans call autumn" , "A season in the US" .)
