Pronunciation

  • /ve.lo.t͡ʃiˈta/[1]

Forms

velocità f (invariable)[1]

Etymology

It is borrowed from Latin vēlōcitās (“speed”), a learned word, from the accusative vēlōcitātem.[2][1][3][4] The Latin noun is derived from vēlōx (“swift, quick”) with the suffix -tās, and Italian has the adjective as veloce.[5][6][7] Old Italian also had the full forms Old Italian velocitade and Old Italian velocitate.[8][9][10]

De Vaan suggests that vēlōx meant “wind-like”, from a noun Proto-Italic *wēlo- (“wind”) built on the root Proto-Indo-European *h₂weh₁- (“to blow”), the root of ventus (“wind”); he notes that Italic has no present verb from this root, so the noun would be a very old derivative.[11]

Earliest recorded meaning

Dante uses velocitade once, in the Convivio (1304–1308).[8][2] The form velocità is first found in Boccaccio (1341–1342), in the sense “swiftness”: a girl who ran so fast that she seemed to leave the winds behind.[8][3]

Semantic evolution

In the 17th century the word became a term of physics: Galileo used it in 1638 for the ratio between the distance covered and the time taken, and his principle that a falling body grows in speed in proportion to its distance from the start.[8][3] Tommaseo distinguished it from its synonyms: velocità for movement, celerità for both movement and action, rapidità for violent motion.[10]

In motor vehicles the word has meant a gear since 1965 (la terza velocità).[8][9] Railway language has grande and piccola velocità for faster and slower goods transport, and alta velocità for the high-speed network.[12][7] In athletics and cycling it names sprint races.[12][1]
