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' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'phase' going around 'r' is 'PHRASE'.
'form' is the link.
I am not very happy about this link. 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" .)
