Etymology

The word for the ford is inherited from Latin vadum (“shallow water, ford”), a relative of vādō (“to go”).[2][3][4][5] Its initial ⟨gu-⟩, where Latin /w/ would normally give Italian /v/, is put down to the influence of Frankish *wad, a word of the same remote origin, which merged with the Latin word.[2][3][6][1] The same Germanic treatment is seen in French gué, Occitan gua and Catalan gual, while Spanish vado, Portuguese vau, Romanian vad and Sardinian badu keep the Latin consonant.[3][7][1] The DÉRom accordingly reconstructs a Proto-Romance type with a consonantal initial for most of the Romance area and a type with a vocalic initial for a continuous area that includes Gallo-Romance.[8]

Old Italian also had the unaffected form vado, used by Jacopone and Petrarch, and Tuscan place names are mostly ⟨Vado⟩ (from 1028), with ⟨Guado⟩ from 1222.[9] The southern dialects kept /v/ as well, with shifted senses: Sicilian vadu means a crack in a wall.[7][1]

The Latin word goes back through Proto-Italic *waðom to Proto-Indo-European *uh₂dʰóm, from the root Proto-Indo-European *weh₂dʰ- of the verb; Proto-Germanic *wadą (“ford”) has the same source, and the Germanic cognates include Old High German wat and German Watt (“mudflats”).[1][3][5]

Earliest recorded meaning

The first record is in Bono Giamboni, who died before 1292, with the sense of a shallow stretch of a river that can be crossed on foot, on horseback or in a vehicle.[2][4] The verb guadare “to ford” appears in the same author.[2]

Semantic evolution

Old Italian also used guado for a passage in general (Jacopone) and for the bottom of the sea or a shoal.[9][10][11] Dante gives it an abstract sense in colui che sì nasconde / lo suo primo perché, che non li è guado (“him who so hides his first reason that there is no ford to it”).[4][12]

The phrase essere in mezzo al guado, to be halfway through a difficult transition, has had some success in contemporary Italian.[2][4][11] In motoring, altezza di guado is the greatest depth of water a vehicle can drive through.[12] The word is common in place names.[2]

guado m (plural guadi)[1]

Etymology

The word for woad is borrowed from Lombardic *waid (“dye plant”), the Lombardic name of the plant.[2][3][4][13][17] DEI places it first in Lombardy and the western Veneto, from where it passed into the standard language.[18] It is akin to Old High German weit and German Waid.[3][18][7]

The word spread easily, DELI notes, because the Latin name of the dye plant, Latin vitrum, was also the word for “glass”.[2] A related Germanic base, Proto-Germanic *waizda-, lives on in Gallo-Romance, where Medieval Latin wasdus appears in the Capitulare de villis: from it come Old French guesde, modern French guède, and Occitan gaida.[2][3][18][7]

Earliest recorded meaning

The first record is a Pistoian document of 1240–1250, in which the word names the blue dye extracted from the plant and used to dye cloth;[17] Old Italian forms include guato and guatu.[17] DELI dates the name of the plant from Florentine texts of 1274.[2]

Semantic evolution

DELI cites studies on the production of woad and the trade in it in the Middle Ages.[2] Older writers also called it guadone and glasto.[9][10] Tommaseo's dictionary describes how the leaves were cut for dyeing when they began to turn violet, and Zingarelli records dare il guado, to dye blue with woad.[10][11]

Its colouring matter is the same as that of indigo.[12] Devoto–Oli describes the dye as one that was extracted from the plant in the past.[13]

Timeline

  • 10th century – Medieval Latin wasdus appears in the Capitulare de villis.[2][18]
  • 1240–1250 – A Pistoian document uses guado for the blue dye.[17]
  • 1274 – Florentine texts name the plant.[2][4]
