This article describes ‘The Taxonomy Dictionary’, a resource that can enhance the spelling engine of a text editor such as Word, so that it can correctly spell every taxon described and listed in the largest taxonomy databases. It contains around 1.4 million unique words, and once installed an incorrectly spelled taxon will be marked by the spelling engine and it will suggest possible correct spellings. Installation instructions for Firefox, LibreOffice and Microsoft Word can be found on the GitHub repository. The software is licensed with a GPL3 licence.
