Sword dance of the bears (5)
I believe the answer is:
sabre
'sword' is the definition.
(sabre is a kind of sword)
'dance of the bears' is the wordplay.
'dance of' indicates an anagram (I've seen 'dancing' mean this).
'bears' is an anagram of 'SABRE'.
(Other definitions for sabre that I've seen before include "Type of sword" , "Bares (anag.)" , "Sword (that may be rattled)" , "Large wasp" , "Walt --, cartoonist" .)
