Forms

quanto (feminine quanta, masculine plural quanti, feminine plural quante)[1] In the singular it may be elided before a vowel: quant'è?.[2][3] Old Lombard has an unstressed form quan.[4][5]

Etymology

It is inherited from Latin quantus (“how great, how much”), with the adverb from its neuter quantum.[6][7][8][9] The Latin word is formed from quam (“how, as”), which belongs with quis (“who”) (see chi), and is the correlative of tantus (“so great”).[6][7][10][5] Wiktionary gives as an alternative Proto-Indo-European *kʷéh₂onts (“how much, how many”).[1] Umbrian panta has the same formation.[10]

The word is panromance: French quant (only in ⟨quant à⟩ “as for”), Occitan cant, Catalan quant, Spanish cuanto, Sardinian cantu and Romanian cât.[7][11]

Earliest recorded meaning

DELI's earliest record is the comparative use, “as much as”, in a Florentine bankers' account book of 1211.[6] The relative “all those who” follows in Patecchio in the 12th or 13th century, and “all that” in Giacomo da Lentini before 1250.[6][7]

Semantic evolution

The interrogative adjective is in the Novellino at the end of the 13th century: “Quanti cavalieri sono quelli che fanno questa uccisione?” (How many knights are those doing this slaughter?).[6][5] The exclamative use is in Bono Giamboni before 1292, and the noun il quanto “quantity” in Dante, as in “nel quale e nel quanto” (in quality and in quantity, Paradiso 2).[6][12] In Florence in the 14th and 15th centuries it could also mean “likewise”.[4]

From it come quantità, at the end of the 13th century, quantunque “although” before 1342, and quantomeno, written as one word from 1948.[6] Many conjunctions and phrases are built on it: in quanto, per quanto, quanto a and quanto basta.[8]

Etymology

The physics term is borrowed from German Quantum, a word that the German physicist Max Planck introduced in 1900 in the form New Latin quantum for the amount of energy given off by an atomic particle.[7][6][2] The GDLI calls it a learned rendering of the scientific Latin word.[15] That form is quantum, the neuter of quantus, used as a noun.[14][1]

Earliest recorded meaning

GRADIT and Nocentini date it to 1927;[8][7][6] DELI's first record is the Enciclopedia italiana of 1929.[8][7][6]

Semantic evolution

The adjectives quantistico and quantico are recorded from 1930 (Nocentini dates quantistico to 1924), and quantizzare from 1959.[6][7] Carlo Emilio Gadda wrote of admiring in Proust a sense of relativity that is like the method of modern fisica dei quanti.[15]
