Theatrical company texted you to appear in A Figure of Speech (6)
I believe the answer is:
troupe
'theatrical company' is the definition.
(acting troupe)
'texted you to appear in a figure of speech' is the wordplay.
'texted you' becomes 'U' (short for 'you' in text messages).
'to appear in' is an insertion indicator.
'a figure of speech' becomes 'trope' (trope can mean a figure of speech).
'u' going inside 'trope' is 'TROUPE'.
(Other definitions for troupe that I've seen before include "Our pet (anag) - company of performers" , "Performing company" , "Group of performers" , "Travelling company of actors" , "Group of entertainers" .)
