Frolicking bears may suggest this dance (5)
I believe the answer is:
sabre
'suggest this dance' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'frolicking bears' is the wordplay.
'frolicking' is an anagram indicator.
'bears' anagrammed gives 'SABRE'.
'may' is the link.
Can you help me to learn more?
(Other definitions for sabre that I've seen before include "Heavy cavalry sword" , "Sword (that may be rattled)" , "Sword with curved blade" , "Type of sword" , "weapon" .)
