Did You Know?

Verb

In 1703, the dedication of the City and County Purchaser and Builders Dictionary included the following words: "These your extraordinary Favours … seem to Postulate from me … a Publick Recognition." That's also how the verb "postulate" was used when English speakers first began using it back in the late 1500s, as a synonym of "require" or "demand." (The word's Latin grandparent, postulare, has the same meaning.) "Postulate" was also used as a noun in the late 1500s, with the meaning "demand" or "stipulation." That sense is now considered archaic, but we still use the noun "postulate." Today, it usually means "a hypothesis advanced as an essential presupposition, condition, or premise of a train of reasoning."
