- vernacular (adj.)
- c.1600, "native to a country," from Latin vernaculus "domestic, native," from verna "home-born slave, native," a word of Etruscan origin. Used in English in the sense of Latin vernacula vocabula, in reference to language.
For human speech is after all a democratic product, the creation, not of scholars and grammarians, but of unschooled and unlettered people. Scholars and men of education may cultivate and enrich it, and make it flower into the beauty of a literary language; but its rarest blooms are grafted on a wild stock, and its roots are deep-buried in the common soil. [Logan Pearsall Smith, "Words and Idioms," 1925]
