Glossary

Key terms and definitions used across technical writing and documentation.

This page is a growing glossary of terms and acronyms used in technical writing, documentation, and related fields. It’s intended to help writers quickly identify unfamiliar language and understand how a term is being used in context.

You can search by acronym, term, context, or definition, or sort the table by term or acronym. Because many terms are used differently across industries and disciplines, context is included to help distinguish between similar or overlapping meanings.

To build and expand this glossary at scale, AI tools have been used to help generate and organize content. These tools are used carefully and reviewed, but they are not perfect. If you notice something that’s unclear, incorrect, or missing, your feedback is welcome.

If you know of a term or acronym that should be included, feel free to send it: admin@twi-net.org.
