All together vs Altogether: Quick Explanation and Sentence Examples

These terms have different meanings and slightly different, but overlapping grammar.

Altogether is an adverb meaning “completely” or “really”; it mainly modifies adjectives, but it can be used to modify other verbs:

Modifying adjectives:  War is usually an altogether bad idea.
Modifying verbs:  I altogether failed that test.

All together forms an adjective or adverb phrase combining all and together:

Just remember that altogether is a unique word meaning “completely” or “very,” while all together simply combines the meanings of all and together.
