Updated: 2026-10-22

## Definition

to separate from a main road, path, or topic and go in a different direction. You use this when one thing splits into two parts.

For teachers: to diverge from a primary route, structure, or subject of discussion. The verb is typically intransitive and describes the point of physical or thematic separation.

## Examples

- The small path branches off to the left.
- About two miles down the main highway, a narrow dirt road branches off toward the coast.
- The discussion on urban planning began to branch off into a debate regarding the ethics of gentrification and historical preservation.

## Pitfalls

- Not "The company decided to branch off into new markets." but "The company decided to branch out into new markets." — Learners often use 'branch off' when they mean 'branch out' to describe business expansion or trying new activities.

## Usage notes

- Usually used without a direct object or followed by 'from' to indicate the source of the split.
- Teaching tip: Contrast with 'branch out', which refers to expanding one's activities or business interests rather than a physical or thematic separation.
