In which to read of cosmic explosion? (6)
I believe the answer is:
comics
'in which to read' is the definition.
Although both the answer and 'in' are nouns, they are not in the same form of the noun.
'cosmic explosion?' is the wordplay.
'explosion?' indicates anagramming the letters (I've seen 'explosion' mean this).
'cosmic' anagrammed gives 'COMICS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for comics that I've seen before include "funny material" , "Children's magazines" , "Funny performers" , "Entertainers" , "Funny men on stage" .)
