## Definition

a short way to write 'thanks' in text messages or online. You use it when you want to be quick and casual with your friends.

For teachers: a non-standard orthographic abbreviation for 'thanks'. Used primarily in digital communication to express gratitude in a highly informal manner.

## Examples

- I got the files, thx.
- He sent a quick text saying 'thx for the help' after I finished moving his boxes.
- While common in instant messaging, using 'thx' in a professional email might make the sender appear lazy or disrespectful to a senior colleague.

## Pitfalls

- Not "Dear Sir, thx for the job offer." but "Dear Sir, thank you for the job offer." — This abbreviation is too informal for professional correspondence and should be replaced with 'thank you'.

## Usage notes

- Typically used in text-based digital communication; not used in spoken English or formal writing.
