What’s the easiest way to build a searchable online dictionary?

If you want something public without learning much code, an AI-assisted site builder can generate a basic version from your word list. Just review everything it creates and make sure you have a reliable way to edit and back up the entries. For a long-term project, learning some JavaScript and basic data management will give you more control.

With only around 700 entries, you probably don’t need a database at first. You could store the words, definitions, and examples in a JavaScript array or JSON file, then filter that data as the visitor types. A searchable select component such as Tom Select could provide suggestions and link each result to a definition page. This would be relatively lightweight and inexpensive to host.

A beginner-friendly content management system could work well here. Create one entry for each word, then use its built-in search and link each result to the corresponding entry. Some systems also have autocomplete or filtering extensions. This avoids building the whole backend yourself, although you may still need a small amount of configuration.

Since this is documenting a vulnerable language, consider speaking with a linguistics department or language-preservation group. They may be able to help with grammar, pronunciation, transcription, backups, and archiving—not just the website. Preserving the surrounding language information can be just as valuable as publishing the word list.

The search box itself is easy; the important part is deciding how the data and pages should work. Think about whether results should appear while typing, whether definitions should open on one page or have separate URLs, and how you’ll update the dictionary later. A JSON file is a good starting point, but if several people need to edit entries or the project grows, a content management system or database will be easier to maintain.
