Unable to decide, laid low, regularly getting wind (7)
I believe the answer is:
tornado
'wind' is the definition.
(I've seen this before)
'unable to decide laid low regularly' is the wordplay.
'unable to decide' becomes 'torn' (I've seen this in another clue).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'laid'+'low'='laidlow'
The alternating letters of 'laidlow' are 'ado'.
'torn'+'ado'='TORNADO'
'getting' acts as a link.
(Other definitions for tornado that I've seen before include "Strong wind" , "Violent whirling wind" , "Dreadful blow" , "A major blow" , "Windy hazard" .)
