Live movement capturing a couple of lines related to dance (8)
I believe the answer is:
balletic
'dance' is the definition.
(thesaurus)
'live movement capturing a couple of lines' is the wordplay.
'live' becomes 'be' (synonyms).
'movement' becomes 'tic' (I've seen this in other clues).
'capturing' indicates putting letters inside.
'couple of lines' becomes 'll' (two abbreviations for line).
'be'+'tic'='betic'
'a'+'ll'='all'
'betic' going around 'all' is 'BALLETIC'.
'related to' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for balletic that I've seen before include "Like Swan Lake" , "Artfully flexible" , "graceful" .)
