Drip means to be transformed into superhero (9)
I believe the answer is:
spiderman
'superhero' is the definition.
Both the answer and definition are singular nouns.
Maybe there's an association between them I don't understand?
'drip means to be transformed' is the wordplay.
'to be transformed' indicates an anagram.
'drip'+'means'='dripmeans'
'dripmeans' with letters rearranged gives 'SPIDERMAN'.
'into' is the link.
Can you help me to learn more?
(Other definitions for spiderman that I've seen before include "Cartoon and film hero, kind of male arachnid" , "building worker" , "Cartoon-cinema hero of arachnid origin" , "suited vigilante" , "Film/comic book hero" .)
