Was returning after dance? It can be puzzling! (6)
I believe the answer is:
jigsaw
'it can be puzzling' is the definition.
The definition suggests a singular noun which matches the answer.
'was returning after dance?' is the wordplay.
'returning' says the letters should be written in reverse.
'after' is a charade indicator (letters next to each other).
'dance?' becomes 'jig' (jig is a kind of dance).
'was' backwards is 'saw'.
'saw' put after 'jig' is 'JIGSAW'.
Can you help me to learn more?
(Other definitions for jigsaw that I've seen before include "Woodcutter" , "Puzzle in which pieces must be reassembled" , "Kind of puzzle" , "Puzzle - powered cutter" , "As pastime" .)
