Etymology
Etymologists say that English speakers derived the word infinitesimal from the Latin word infinitesimus, which means "most infinite." The term was first introduced into English in 1656 by the philosopher and scientist Robert Boyle. We still use infinitesimal today to describe nanoscopic, microscopic, or minute objects that cannot be seen or perceived with the naked eye.
