Turning rainy - got unsettled (8)
I believe the answer is:
gyration
'turning' is the definition.
(I've seen this before)
'rainy got unsettled' is the wordplay.
'unsettled' indicates an anagram.
'rainy'+'got'='rainygot'
'rainygot' anagrammed gives 'GYRATION'.
(Other definitions for gyration that I've seen before include "Tory gain (anag) - revolution" , "Going round" , "Revolution, rotation" , "Turning" , "Spin" .)
