wand

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

'staff' is the definition.
(wand is a kind of staff)

I can't explain the rest of the clue.

(Other definitions for wand that I've seen before include "Magic baton" , "Fairy's stick" , "Christmas tree fairy's rod" , "Sorceror's magic stick" , "Magician's stick" .)

I've seen this clue in The Telegraph.
