What part of speech is without?

"Without" can be a few different parts of speech depending on how it's used in a sentence:

* Preposition: This is the most common use. It indicates a lack of something or a state of being apart from something.

* Example: "I can't go without my phone."

* Adverb: This is less common but possible. It functions as an adverb of negation, meaning "not" or "not having."

* Example: "The dog ran without stopping."

* Conjunction: This is the least common use. It acts as a conjunction meaning "except."

* Example: "Everyone was there without John."

The specific part of speech will depend on the context of the sentence.
