grotto

Etymology

It is borrowed from Italian grotta,^{[2][3][4][5][6]} from the popular Latin forms *crupta and *grupta,^[2][4][6] for Latin crypta (“vault, cavern”),^[2][3][5] from Ancient Greek κρύπτη (krúptē, “hidden place, vault”),^[2][3][7] from κρύπτειν (krúptein, “to hide”).^[2] It is thus a doublet of crypt.^[4][7] The English ending -o is not fully explained: the OED says Dante also used the form grotto,^[2] Etymonline and Barnhart point to the spelling in foreign translations or editions of the “Divine Comedy”,^[3][4] and Barnhart adds that a concordance to Dante does not attest it.^[4] The same Latin word gave Old French crote, Old Occitan crota, Spanish gruta and Portuguese gruta,^[2] while French grotte comes from the Italian.^[2][7] From that French form English had already taken grot (1507), and Ayto treats grotto as replacing it in the 17th century,^[7][4] though Barnhart finds a connection between them hard to establish.^[4] The Italian noun also gave grottesco (“of a cave”), through French the source of grotesque.^[3]

Earliest recorded meaning

A cave, especially a picturesque one: 1617, in S. Collins's Epphata to F. T.^[2][4][5] Etymonline dates the word to the 1610s.^[3]

Semantic evolution

By 1625, in Bacon's Essayes, the word was also used of a cave made by hand, often decorated with shells, as a cool retreat,^[2][8] and in the 18th century such constructions were a feature of landscaped gardens.^[9] Johnson (1755) defined it as a cave made for coolness, and held that it was not properly used of a dark, horrid cavern.^[10] In the 19th century London street boys built grottoes of oyster shells and showed them on 5 August, the feast of St James of Compostella.^[8][2] The Oxford Dictionary of English also has an indoor structure resembling a cave, such as one where children visit Father Christmas.^[11] Merriam-Webster also records grotto, or grotto blue, as the name of a greenish blue colour.^[5]
