Did you know?
We are not opining—that is, expressing our opinion—when we say that opine is not a back-formation of opinion, though the two words do share a common ancestry. A back-formation is a word formed by the subtraction of part of an existing word; for instance, the verb bartend is a back-formation of the noun bartender. Opine and opinion, however, both entered English independently, taking different routes from their mutual roots in the Latin verb opīnārī, meaning “to have in mind” or “to think.” Opinion arrived in the 14th century, while opine followed about a century later.
