altogether

Altogether

[awl-tuh-geth-er, awl-tuh-geth-er]
Though they're both adverbs, altogether and all together have very different meanings. Altogether means "completely" or "entirely," synonymous with the phrase, "all things considered." The word is a variant of the Middle English altogeder, referring to "the whole." All together refers to a group of people or things that act collectively or at the same time, e.g. "Let's raise our glasses all together!"
