The NWN Lexicon is a community-based language reference and resource guide for BioWare’s Neverwinter Nights role-playing game, including the Enhanced Edition. Its central offering is documentation for NWScript, the game’s scripting language, designed to be complete, concise, and easy to use. The Lexicon organizes information on functions, constants, data types, events, and related topics, and includes tutorials, primers, resources, and code examples to support script writers and module creators.

The project continues to develop through corrections and knowledge shared by the Neverwinter Nights community. Contributors are invited to help improve the reference and provide small, working script examples, with collaboration coordinated through the Neverwinter Vault Discord. The site also points users to other wikis for additional modding, engine, and gameplay information.

For those who prefer desktop access, an offline project provides a scraped HTML version of the Lexicon, though it is updated infrequently. Maintained by the NWN Lexicon Group, the content is available under the GNU Free Documentation License, subject to stated exceptions
