Hack covers page with sensational news feature (6)
I believe the answer is:
splash
'sensational news feature' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'hack covers page' is the wordplay.
'hack' becomes 'slash' (slash can mean to hack or chop).
'covers' indicates putting letters inside.
'page' becomes 'p'.
'slash' enclosing 'p' is 'SPLASH'.
'with' is the link.
Can you help me to learn more?
(Other definitions for splash that I've seen before include "big front page news" , "Noise of a body falling into water" , "Big media display -- bellyflop effect" , "Ostenatious display made by spatter of water" , "Sound of dive" .)
