Cut listener being introduced to cast (7)
I believe the answer is:
sheared
'cut' is the definition.
(synonyms)
'listener being introduced to cast' is the wordplay.
'listener' becomes 'ear' (I've seen this before).
'being introduced to' means one lot of letters goes inside another.
'cast' becomes 'shed' (synonyms).
'ear' put within 'shed' is 'SHEARED'.
(Other definitions for sheared that I've seen before include "Adheres (anag.)" , "Cut wool off (a sheep)" , "Removed fleece" , "As sheep perhaps" , "Clipped" .)
