Animated actors on strange form (8)
I believe the answer is:
cartoons
'strange form' is the definition.
Although both the answer and 'form' are verbs, they are not in the same form of the verb.
'animated actors on' is the wordplay.
'animated' is an anagram indicator.
'actors'+'on'='actorson'
'actorson' with letters rearranged gives 'CARTOONS'.
Can you help me to learn more?
(Other definitions for cartoons that I've seen before include "Animated films or humorous drawings" , "Amusing and often pointed drawings in newspapers" , "Humorous or satirical drawings" , "Comic drawings, may be animated" .)
