Is init a word in slang?

While "init" isn't a standard word in formal English, it is a slang term in certain dialects, primarily in the UK. It's short for "it" and used as a pronoun, similar to "it is" or "that is."

For example:

* "Init, mate?" (Meaning: "Is that right, mate?")

* "Init a good day." (Meaning: "It's a good day.")

However, "init" is considered informal and regional and might not be understood by everyone. It's more common in spoken language than written.
