Eviternity is a noun that means eternal duration.

The Latin word aeviternus (EYE vee ter nal) means ‘everlasting.’ By the late 16th century, our word of the day underwent a few changes and joined the English language. Here’s an example of it in use:

The wait for my uber car seemed to last an eviternity. In reality, the duration was eternal. It just felt that way because it was so cold outside.
