Suspect a huge disco has no good music for a rave? (4,5)
I believe the answer is:
acid house
'a rave?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'suspect a huge disco has no good music' is the wordplay.
'suspect' indicates an anagram (a suspicious or unusual spelling).
'has no' is a deletion indicator.
'good' becomes 'g' (abbreviation).
'music' becomes 'a'.
'huge'+'disco'='hugedisco'
'hugedisco' with 'g' taken out is 'huedisco'.
'huedisco'+'a'='huediscoa'
'huediscoa' is an anagram of 'ACID HOUSE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for acid house that I've seen before include "scene from the 1980s?" , "loud music" , "scene from the eighties?" , "youth movement" , "music? No - with 9a" .)
