Did you know?

Is it human to err?

Many people are familiar with the word err from encountering it in the epigram “to err is human; to forgive, divine.” This phrase is found in Alexander Pope’s An Essay on Criticism, from 1711. Earlier expressions of the same sentiment exist, as in Thomas Jones’ 1678 book, Of the Heart, and its Right Soveraign, which contains the line “to err, is human, to recover, is Angelical; to persevere is Diabolical.”

Err is also often found in the phrase err on the side of caution, to suggest that being overly cautious is better than not being cautious enough.

Err stems from the Latin word errare, meaning “to stray, wander,” and it retained that meaning when it first entered English. We find the same Latin ancestor at the root of the words error, erratic, and erroneous.
