rotunda

Etymology

It is borrowed from Latin rotunda, the feminine of rotundus (“round”), as used in Sancta Maria Rotunda, the name of a church occupying the Pantheon in Rome, recorded from the 12th century or earlier, and it was originally modelled on Italian rotonda.^[2] Most other dictionaries make it an alteration of the Italian noun under the influence of the Latin form.^{[3][4][5][6][7][8][9]} The Italian word is a noun use of the feminine of rotondo (“round”),^[3][2][10] and is recorded from the 16th century, in 1547 as ritonda with reference to the Pantheon.^[2] The Oxford Dictionary of English takes the Italian noun as short for a phrase with camera (“chamber”).^[7] The Latin adjective is from rota (“wheel”).^[11][12][9]

Earliest recorded meaning

The name of a circular building, in early use the Pantheon at Rome: about 1566, in W. P.'s translation of Curio's Pasquine in Traunce.^[2][4] Other dictionaries begin it later: Barnhart in 1611, with Coryat's Crudities,^[3] and Etymonline in the 1680s.^[11]

Semantic evolution

The word first named a particular building, and Etymonline stresses that it typically meant the Pantheon, the most celebrated building of the kind.^[11] From 1648 it was used generally of any building circular inside and out, especially a domed one.^[2] Rival forms appeared alongside it: rotundo from 1614 and rotonda from 1620.^[2] From the 18th century the word moved indoors, to a circular hall or room within a building: 1737 in the OED and 1780 in Etymonline.^[2][11] In North America it was applied from 1847 to the main hall of a public building, often one with a domed ceiling.^[2] In 1927 it is recorded as the name of a rounded Gothic typeface, after a script of the 13th century.^[2]
