Ludicrously odd performance as an act in variety (5)
I believe the answer is:
antic
'ludicrously odd' is the definition.
(I've seen this in another clue)
'act in variety' is the wordplay.
'variety' indicates an anagram.
'act'+'in'='actin'
'actin' anagrammed gives 'ANTIC'.
'performance as an' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for antic that I've seen before include "Prank" , "Caper, trick" , "Caper; grotesque (arch.)" , "Absurd action" , "Absurd act" .)
