razzo

Forms

razzo m (plural razzi)^[1]

Etymology

It is inherited from Latin radius (“ray; spoke”), the Umbrian and central-southern outcome of the word that gave Tuscan raggio.^[2][3][4][1] Vulgar Latin *radjus was treated like medius, which gave mezzo, and Nocentini compares the pair moggio and mozzo.^[5][3] Outside Tuscany, Arezzo excepted, the form was in literary use from the earliest centuries, and it also turns up at Lucca and Pistoia.^[2] Besides that inherited word, its doublets are radio, borrowed from Latin, and rai, from Occitan.^[1]

The sense “rocket” comes from the way fireworks shoot off like rays; it then passed to any vehicle driven in the same way.^[2][3][6] The same Latin word is French rai, Occitan rai, Catalan raig, Spanish rayo and Romanian rază.^[7]

The origin of the Latin word is unclear.^[8][9] De Vaan thinks it unlikely to belong with Latin rādīx (“root”), and its initial ⟨rad-⟩ may reflect a root for which there is no clear candidate.^[8][9]

Earliest recorded meaning

In the sense “ray” the word is recorded from the end of the 13th century;^[4][3][2] Dante and Cenne da la Chitarra used it.^[4][3][2] Dante also used it for a glance: de' suoi razzi sovra 'l meo cor piove / tanta paura “from her rays such fear rains on my heart”.^[4][10]

Semantic evolution

The firework is first named in 1516, in Ariosto's Orlando furioso: Non van sì presto i razzi fuor di mano “rockets do not leave the hand so fast”.^[2][11] Biringuccio's Pirotechnia describes thousands of razzi of various kinds, some rising high and bursting into four or six more.^[11]

In the early 20th century D'Annunzio used the word for a self-propelled projectile, and in 1959 it named the rocket engine.^[2] The phrase a razzo “like a rocket” means at great speed (partire a razzo).^[4][12][13] Retrorazzo “retrorocket” followed in 1965.^[3]

The sense “spoke of a wheel” is shared with razza (1640), from the Latin neuter plural radia read as a feminine singular.^[3][7]

Usage notes

In the sense “rocket” the z is voiced (/dz/).^[1][10] A separate razzo with a voiceless z is the aphaeretic form of arazzo “tapestry”, used in the 14th–16th centuries, often as panni di razzo; in Venice it named the woollen hanging of a gondola's cabin.^{[4][11][15][16]}
