Fab McCartney, perhaps with introduction from Ringo (7)
I believe the answer is:
stellar
'fab' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'mccartney perhaps with introduction from ringo' is the wordplay.
'mccartney perhaps' becomes 'Stella' (Stella McCartney is a fashion designer).
'with' says to put letters next to each other.
'introduction from' indicates taking the first letters.
The first letter of 'ringo' is 'r'.
'stella'+'r'='STELLAR'
Can you help me to learn more?
(Other definitions for stellar that I've seen before include "Like highlights" , "Relating to the stars" , "High-class" , "Starry" , "Outstanding -- star-like" .)
