• All = everyone or everything

Main Difference Between Altogether and All Together

Grammar Rule Section

Understanding the grammar behind these expressions makes choosing easier.

Altogether as an Adverb

Altogether modifies verbs, adjectives, or entire sentences.

Examples:

• She was altogether unaware of the problem.
• The results were altogether different.
• There were ten people altogether.

It often appears when summarizing or making a final statement.

All Together as a Phrase

All together works as a combination of an adjective-like word and an adverb.

Examples:

• The players stood all together.
• They worked all together on the assignment.
• The songs were performed all together.

The phrase usually involves a group performing an action at the same time.

Origin and Etymology

The word altogether developed from the Old English phrase meaning “all in one” or “completely.” Over time, the separate words merged into a single adverb.

The word comes from the combination of:

• All: meaning whole, entire, every
• Together: meaning united or in company

English gradually combined many frequently used phrases into single words, and altogether became a standard spelling.

The phrase all together remained separate because it continued to express the literal idea of “all being together.”
