Ran wild amidst commotion in dangerous weather (7)
I believe the answer is:
tornado
'dangerous weather' is the definition.
(I've seen this in another clue)
'ran wild amidst commotion' is the wordplay.
'wild' indicates an anagram.
'amidst' is an insertion indicator (amidst can mean between or within).
'commotion' becomes 'todo' (synonyms).
'ran' with letters rearranged gives 'rna'.
'rna' placed within 'todo' is 'TORNADO'.
'in' is the link.
(Other definitions for tornado that I've seen before include "squall" , "RAF fighter; whirlwind" , "Violent rotating windstorm" , "Violent wind storm" , "Destructive windstorm" .)
