cellula

Forms

cellula f (plural cellule)^[1] The old form Old Italian cellola is recorded beside cellula.^[2][3]

Etymology

It is learned: it is borrowed from Latin cellula (“small room”), the diminutive of cella (“storeroom, small room”).^[4][5][6][3] The LEI calls it a Late Latin word, while de Vaan records it as “small room” from Terence on.^[3][7] Sabatini–Coletti derives the biological sense from scientific Latin, and Wiktionary dates the learned borrowing to the 17th century.^[8][1] The same Latin word is French cellule and Spanish célula.^[5][9]

DEI says that the name for the unit of living matter was proposed by the English physicist Robert Hooke.^[9] The LEI notes that in this scientific sense the word became important in every European language of culture.^[3]

De Vaan reconstructs a Proto-Italic stem for the base noun and asks whether it continues Proto-Indo-European *ḱēl- (“hiding”).^[7] He suggests that it may come from an older *cēla and keep the long-vowel base of cēlō (“to conceal”).^[7]

Earliest recorded meaning

The TLIO's first record is in the Storie de Troia e de Roma, a Roman text of 1252–1258, with the sense “an enclosed room, a small space indoors”.^[2] The LEI dates the same text to the end of the 13th century.^[3]

Semantic evolution

In Old Italian the word also meant a small cell used for penance, and in medicine each of the three chambers into which the brain was thought to be divided, the seats of the mental faculties.^[2] The Florentine Ottimo commento has cellola in both senses in 1334 and 1340, and the idea of brain cells survived in Goldoni (1761) and Panzini (1921).^[3]

A cavity in an organ is recorded at Padua about 1460, and a small cavity in a body or mineral in Galileo (1630–1631), who writes that the sponge “nelle sue cavità e cellule contiene aria e acqua” (holds air and water in its cavities and cells).^[3][10] DEI dates the biological sense to Malpighi in 1675, and DELI to Pier Antonio Micheli, before 1737.^[9][4]

New senses came in the 20th century: a basic element of a structure (from 1894), the wing structure of an aircraft (from 1916, D'Annunzio) and the smallest unit of the Communist Party (from 1921).^[3] Cellula fotoelettrica was taken from French, and telefono cellulare is a calque of the English cellular phone.^[3]
