Strong wind ruptured flap (7)
I believe the answer is:
tornado
'strong wind' is the definition.
(I've seen this before)
'ruptured flap' is the wordplay.
'ruptured' becomes 'torn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'flap' becomes 'ado' (I've seen this in another clue).
'torn'+'ado'='TORNADO'
Can you help me to learn more?
(Other definitions for tornado that I've seen before include "Whirling storm" , "Dreadful blow" , "squall" , "RAF fighter; whirlwind" , "Cyclone, twister" .)
