Crossword Genius

Purist movement in trouble (4,2)

Ross

I believe the answer is:

stir up

'trouble' is the definition.
(thesaurus)

'purist movement' is the wordplay.
'movement' indicates an anagram (letters move around).
'purist' anagrammed gives 'STIR UP'.

'in' acts as a link.

(Other definitions for stir up that I've seen before include "Get excited" , "Excite - incite" , "Foment (trouble)" , "Cause or provoke trouble" , "Instigate" .)

I've seen this clue in The Globe and Mail.
