Is it something between a gust and a blast? (9)
I believe the answer is:
crosswind
'is it something between a' is the definition.
I can't tell whether this definition defines the answer.
'gust and a blast?' is the wordplay.
'gust' becomes 'cross' (I can't justify this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'a blast?' becomes 'wind' (blast is a kind of wind).
'cross'+'wind'='CROSSWIND'
Can you help me to learn more?
(Another definition for crosswind that I've seen is " it may force you out of your way".)
