Radio’s studied later, after accident or crisis? (3,5)
I believe the answer is:
red alert
'crisis?' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'radio's studied later after accident' is the wordplay.
'radio's' indicates a 'sounds like' (homophone) clue.
'studied' becomes 'read' (to read a subject is to study it at university).
'after accident' indicates anagramming the letters (I've seen this in other clues).
'read' is a homophone of 'red'.
'later' is an anagram of 'alert'.
'red'+'alert'='RED ALERT'
'or' is the link.
Can you help me to learn more?
(Other definitions for red alert that I've seen before include "Severe 1 dn" , "Severe warning" , "Alarm" , "Serious warning" , "High crisis level" .)
