Today’s word: utility.
Utility first showed up in the late fourteenth century, meaning “fact of being useful”. It comes from the Old French utilite, usefulness, and classical Latin utilitatem, which has varied meanings, like useful and beneficial. Utilitatem comes from utilis, useful, and uti, use. And I mean it super comes from use because the word use comes from uti, too.
TL;DR: Utilities are useful things.
