Welcome!

This dictionary's creation was inspired by the need for a reference guide during JWST meetings, where acronyms fly at you like bugs on a highway. It is not a static application, rather it is constantly being improved and the acronyms entries are constantly being updated.

There are two ways to use the dictionary: you can download the (legacy) app (stopped updating in 2015) so that you'll have access to the dictionary even if you don't have internet, or you can use the online version which will always have the most up-to-date list of acronyms.

Have an acronym you want to add? Head on over to our contribute page, where you can submit a new acronym! Or provide a description for an existing acronym!
