“Funnest” or “most fun”—which is correct? It’s a common question asked by many English speakers. The answer is, neither. In English, the only correct form is “most fun.”
The confusion between “funnest” and “most fun” comes from the fact that the former is an example of a “nonstandard” or “informal” use of language. In other words, “funnest” is a slang word, and it’s not considered acceptable in formal writing.
But what about in spoken language? “Funnest” is still considered slang, and it’s best to avoid it in formal situations. However, it is sometimes used in informal contexts, such as among friends or in casual conversations.
It’s important to remember that “most fun” is the only correct form in English. However, if you’re in an informal setting and want to sound more casual, you can use “funnest” if you like. Just don’t use it in formal writing or in any other situation where you need to sound more formal.
