Go by bike, holding on in high wind (7)
I believe the answer is:
cyclone
'high wind' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'go by bike holding on' is the wordplay.
'go by bike' becomes 'cycle' (I've seen this before).
'holding' means one lot of letters goes inside another.
'cycle' enclosing 'on' is 'CYCLONE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cyclone that I've seen before include "Violent whirling wind" , "Violent windstorm" , "Hurricane" , "Tornado" , "Low pressure area or storm" .)
