Looked on wiktionary:
https://en.wiktionary.org/wiki/cobra_effect
and it just says it's a noun. How do you look for coined words on Wiktionary. I want to search for coined words instead of ordinary word like abdomen, which might have been coined by someone, but can be found on a dictionary. Is there a word for composite words? I can only use the category noun to search for coined composite words, but that means I will end up with regular words like abdomen in the search result and it's a problem. I want to be able to search for composite coined terms like Cobra Effect.
