Rent trouble? That's potentially destructive (7)
I believe the answer is:
tornado
'potentially destructive' is the definition.
I can't judge whether this defines the answer.
'rent trouble?' is the wordplay.
'rent' becomes 'torn' (synonyms).
'trouble?' becomes 'ado' (both can mean bother or commotion).
'torn'+'ado'='TORNADO'
'that's' is the link.
Can you help me to learn more?
(Other definitions for tornado that I've seen before include "RAF fighter; whirlwind" , "lot of wind" , "Donator of fierce wind" , "Terrible current" , "Destructive windstorm" .)
