Commonly Confused

The forms altogether and all together, though often indistinguishable in speech, are distinct in meaning. The adverb altogether means “wholly, entirely, completely”: an altogether confused scene. The phrase all together means “in a group”: The children were all together in the kitchen. The word all can be omitted without seriously affecting the meaning: The children were together in the kitchen.

Etymology

Origin of altogether

First recorded in 1125–75; variant of Middle English altogeder; see all, together

Explanation

If you're altogether certain, you know it for a fact. Since you're altogether sure that your calculations are correct, go ahead with the experiment. Please wear your goggles just in case. Never use “all together” (meaning “all in one place”) when you mean altogether (which can also mean "all things considered"). It was risky to bring us all together again after so many years, but you have to admit that altogether we had a good time. Altogether, it could have been worse. It wasn't altogether bad. I suppose we won't do it again next year.
