Performing in just one role with kind acts, running around (8)
I believe the answer is:
typecast
'performing in just one role with kind acts running around' is the definition.
I can't tell whether this definition defines the answer.
'with kind acts running around' is the wordplay.
'with' indicates putting letters inside.
'kind' becomes 'type' (type is a kind of kind).
'running around' is an anagram indicator.
'acts' with letters rearranged gives 'cast'.
'type' going within 'cast' is 'TYPECAST'.
Can you help me to learn more?
(Other definitions for typecast that I've seen before include "in the usual parts" , "Stereotype" , "Put into same kind of role continually" , "Assigned the same kind of role repeatedly" , "Given the same sort of parts" .)
