A few words form the stage, about right (6)
I believe the answer is:
phrase
'a few words' is the definition.
'the stage about right' is the wordplay.
'the stage' becomes 'phase' (both can mean a part or period of something).
'about' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'phase' enclosing 'r' is 'PHRASE'.
'form' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for phrase that I've seen before include "Group of words as unit" , "Present" , "Articulate, couch" , "a certain expression" , "Put into words" .)
