Tell I am getting a role (6)
I believe the answer is:
impart
'tell' is the definition.
(I know that impart is a more specific form of the action tell)
'i am getting a role' is the wordplay.
'i am' becomes 'I'm' (contraction).
'getting' means one lot of letters go next to another.
'a role' becomes 'part' (eg a part or role in a film).
'im'+'part'='IMPART'
(Other definitions for impart that I've seen before include "Contribute" , "Make known, relate" , "Give - convey" , "Divulge, inform" , "Pass on information" .)
