## Definition

to connect something to a larger system or power supply; it can also mean to get involved with a group or activity.

For teachers: to establish a connection with a larger network, system, or organization; often used in technical contexts for hardware/software or metaphorically for social integration.

## Examples

- You need to hook into the main power grid.
- The new software allows users to hook into existing databases without changing their current workflow.
- By providing an open API, the platform encourages third-party developers to hook into the ecosystem and build custom tools.

## Pitfalls

- Not "He hooked into the computer to the wall." but "He hooked the computer into the wall." — when used with an object being connected, the object usually comes before 'into' if the verb is used transitively.

## Usage notes

- often used with technical systems, networks, or social communities as the object.
- Teaching tip: contrast with 'hook up' which focuses on the act of connecting two things, while 'hook into' emphasizes becoming part of a larger, pre-existing structure.
