promontory

Etymology

It is borrowed from Latin prōmontorium,^[2][3][4] a variant of prōmunturium (“headland, promontory, spur of a mountain ridge”),^[2][3][5] altered under the influence of mōns (“mount, mountain”).^{[6][7][8][3][5]} The OED treats prōmontorium as classical Latin, while Hoad, Klein, Barnhart, Etymonline and the Shorter Oxford call it Medieval Latin.^{[2][9][5][7][8][10]} Barnhart and Etymonline add Middle French promontoire as a second source,^[7][8] which the OED only compares, recording it from 1213 in Old French, beside Spanish promontorio (1490), Portuguese promontório (1563) and Italian promontorio (before 1292).^[2] Most dictionaries relate prōmunturium to prōmineō (“to jut out”), the source of prominent, with varying confidence: "probably" in Etymonline, Barnhart and the American Heritage Dictionary, "perhaps" in the OED.^{[8][7][6][2][5]} Hoad, the Shorter Oxford and Ayto instead derive it from prō- (“forward”) and mōns itself,^[9][10][11] and Dictionary.com calls the derivation unclear.^[12] Ayto adds that the base of prōmineō may itself be related to mōns.^[11]

Earliest recorded meaning

A point of high land jutting out into the sea: 1548, in the translation of Erasmus's Paraphrase of the New Testament by N. Udall and others.^[2] Barnhart and Merriam-Webster also give 1548,^[7][3] and Etymonline the 1540s.^[8]

Semantic evolution

The core sense has not changed since the 16th century.^[2][13] The OED records an extended use from 1603, in G. Owen's Description of Penbrokshire.^[2] Johnson (1755) defined the word as "a headland; a cape; high land jutting into the sea", with quotations from Shakespeare and Milton, and noted a short form promont that he had seen only in Suckling.^[14] Anatomy took the word over for a projection, especially of bone, in 1793;^[2] the Shorter Oxford dates this to the mid 19th century,^[10] and the OED records the same sense in French from 1805.^[2] Merriam-Webster also lists a bluff overlooking a lowland and a low-lying cape.^[3]
