Where do the plurals come from?


Most come from a Wiktionary data dump from February 2017. We have a list of nouns and their corresponding plurals. The volunteers at Wiktionary may have updated some plurals or added new words since then. We'll update every once in a while to match their new information, but if you notice something that seems wrong, let us know.


When we can't find the word in our list of nouns from Wiktionary, we guess using an inflection algorithm callend Inflex. When we guess like this, we'll let you know that we aren't 100% sure of the plural we are providing, but Inflex is often correct anyway.
