“With the surge in popularity of environmental, social and governance (ESG) investing, it has become more important than ever to ensure that related companies and projects are as ‘green’ as they purport to be.” — Zennon Kapron, Forbes, 18 July 2023

The Latin verb portare, meaning “to carry,” was the port of entry for many an English word, from the noun portfolio to familiar verbs report, support, and transport. (The port a ship uses comes from a different Latin source: portus, meaning “port.”) Purport too ultimately comes from portare, although its direct ancestor is the Anglo-French verb purporter, meaning “to carry” or “to mean.” Today, purport is typically used when someone or something makes a claim that may or may not be true; something purported to be a fact is not at all a sure thing. The skepticism that modern purporting generally requires wasn’t present in the original verb, however. In the late 17th century, a purported claim was assumed as true as any. And three centuries before that, to purport a message, idea, etc., was simply to convey it. Purport can also function as a noun with a meaning closely related to the older verb one: it can refer to the main or general meaning conveyed in a piece of writing, in someone’s actions, etc., as in “the purport of the visit” or “the essay’s purport.”
