What part of speech is altogether?

"Altogether" can be two different parts of speech, depending on its use:

* Adverb: When it modifies a verb, adjective, or another adverb, it means "completely" or "entirely."

* Example: "He was altogether exhausted after the long journey."

* Conjunction: When it connects two clauses, it means "in all" or "in total."

* Example: "There were five people at the party altogether."

So, you need to look at the sentence to determine the part of speech.
