Basic actor in difficulty with dramatic movements (10)
I believe the answer is:
acrobatics
'with dramatic movements' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'basic actor in difficulty' is the wordplay.
'in difficulty' indicates an anagram (I've seen this in other clues).
'basic'+'actor'='basicactor'
'basicactor' with letters rearranged gives 'ACROBATICS'.
Can you help me to learn more?
(Other definitions for acrobatics that I've seen before include "pursuit of tumblers" , "What one may see in circus" .)
