Updated: 2026-10-22

## Definition

to move or progress at the same speed as someone or something else so you do not fall behind.

For teachers: to maintain the same pace, level, or progress as another entity. Often functions as an intransitive verb or as part of a three-part phrasal verb with 'with'.

## Examples

- You are walking too fast and I cannot keep up.
- It is difficult to keep up with all the new technology that comes out every year.
- The small local bookstore struggled to keep up with the aggressive pricing strategies and rapid delivery times of its multinational competitors.

## Pitfalls

- Not "I can't keep up the other students." but "I can't keep up with the other students." — When an object follows, the preposition 'with' is required.

## Usage notes

- Often followed by 'with' when an object is mentioned.
- Teaching tip: Contrast with 'keep on' (continue) and focus on the 'with' collocation for the most common usage.
