Popular vocalist captivates with moving delivery (9)
I believe the answer is:
inswinger
'moving delivery' is the definition.
'inswinger' can be an answer for 'delivery' (cricket delivery). I am not certain of the 'moving' bit.
'popular vocalist captivates with' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'vocalist' becomes 'singer' (synonyms).
'captivates' means one lot of letters goes inside another (inserted letters are captured or captivated).
'with' becomes 'w' (short for with).
'singer' going around 'w' is 'swinger'.
'in'+'swinger'='INSWINGER'
Can you help me to learn more?
(Other definitions for inswinger that I've seen before include "Swerving ball" , "swerving delivery" , "ball from fast bowler" , "delivery curling through air" , "moving ball" .)
