Etymology

It is borrowed from Latin prōmontōrium (“headland, promontory”), a variant of prōmunturium.[2][3][1][4] Nascentes calls it a learned word.[5]

The origin of the Latin word is not settled: Houaiss derives it from prō- (“forward”) and mōns (“mountain”).[2] The OLD suggests prōmineō (“to jut out”) with association with the Latin word for mountain, and Lewis & Short also refer it to that verb.[4][6] Wiktionary finds it unclear: the first part is the prefix, the second usually taken as the word for mountain, with a /u/ from vowel reduction, and the spelling with ⟨-torium⟩ looks later than the one with ⟨-turium⟩.[1]

In Spanish promontorio is likewise a Latinism;[7] García de Diego lists popular forms such as tromontorio in Castilian and tresmontorio in Asturian.[7]

Earliest recorded meaning

Houaiss's first record is of 1563, and Cunha dates the word to the 16th century.[2][3] Camões uses it of the Sacro promontório, the Sacred Promontory from which the body of the martyr Vincent was brought to Lisbon, a passage that Vieira quotes;[8][6] Lewis & Short identify the Latin Promunturium Sacrum in Portugal as Cape St Vincent.[8][6]

Semantic evolution

Feijó (1734) defines it as the point of land that juts out over the sea, and Vieira labels it a nautical term for a high cape stretching into the sea.[9][8] The original Caldas Aulete adds two anatomical senses, a small projection in the inner wall of the eardrum and the projection where the sacrum meets the last lumbar vertebra.[10] Houaiss also has a general sense, any high part or prominence.[2]
