## Definition

Stands for Original Equipment Manufacturer. A company that makes parts or equipment that another company then sells under its own brand name.

For teachers: Abbreviation for Original Equipment Manufacturer. A company that manufactures products or components which are subsequently purchased and marketed by another firm under its own brand identity.

## Examples

- The car manufacturer buys its brakes from an OEM.
- Many tech giants rely on an OEM in Asia to produce the hardware for their latest smartphones.
- The shift toward electric vehicles has forced traditional OEMs to re-evaluate their supply chains and invest heavily in proprietary battery technology to maintain a competitive edge.

## Pitfalls

- Not "an OEM part is better than a generic" but "an OEM part is better than a generic one" — When used as a modifier, OEM describes the source; learners often treat it as a standalone noun when they mean 'OEM part'.

## Usage notes

- Often used as a modifier before another noun (e.g., 'OEM parts').
