Pop star's prompt (5)
I believe the answer is:
swift
This clue could be a double definition.
'pop star's' is the first definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'prompt' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for swift that I've seen before include "Expeditious" , "Fast-moving bird" , "Bird; happening quickly" , "wit?" , "Fast - novelist" .)
