sinuous

I'm a little stuck... Click here to teach me more about this clue!

'turning' is the definition.
(thesaurus)

I can't explain the remainder of the clue.

(Other definitions for sinuous that I've seen before include "Lithe, supple; curvy" , "Curving in and out" , "Serpentine" , "Twisting and turning" , "Full of curves, bends" .)

I've seen this clue in The Times.
