Etymology

It is borrowed from Gothic 𐍅𐌰𐌹 (wai, “woe!”) crossed with Latin vae (“alas, woe”), according to Devoto–Oli, Sabatini–Coletti, Devoto and the GDLI;[2][3][4][5][6] Meyer-Lübke likewise lists it under the Gothic word, with Spanish guay and Portuguese guai.[2][3][4][5][6] Devoto explains the initial ⟨gu⟩ by the normal treatment of Germanic /w/ in Gothic and Lombardic loans.[4]

GRADIT, Zingarelli and Gabrielli derive it instead from Frankish *wai, GRADIT through Old French guai, and DEI prefers this route too, but does not rule out Gothic; in either case the Germanic forms were laid over the Latin word.[7][8][9][10] Nocentini sees a convergence: the Latin exclamation, inherited from Indo-European, was used by Jerome in the Vulgate for Ancient Greek οὐαί (ouaí, “woe!”), a Greek rendering of a Hebrew cry, while Wulfila used the Gothic word in his New Testament.[11] The word owes its success to the Bible, above all to the woes Jesus pronounces on the scribes and Pharisees in Matthew 23; Romanian vai, in his view, comes directly from Greek.[11]

De Vaan reconstructs a Proto-Italic *wai for the Latin word and lists Welsh gwae, Old English wā and Old High German wē beside it, but thinks these are probably independent imitative cries, though a common inheritance cannot be excluded.[12]

Earliest recorded meaning

GRADIT and Zingarelli date the first record to about 1224; the GDLI's first quotation is from Saint Francis of Assisi: “Guai a quilli che se trovarà ne le peccata mortali” (woe to those who will be found in mortal sin).[7][8][5] It expressed a threat of punishment or misfortune.[5][11]

Semantic evolution

In Dante's Inferno an old boatman cries to the damned “Guai a voi, anime prave!” (woe to you, wicked souls!).[5][13] Old texts also used guai alone, without a person, as a cry of grief like ahimè, a sense now archaic.[13][2][3] In modern Italian the threat is often weakened to a warning about the unpleasant result of an action, with a and an infinitive or se and a clause.[7][2][14]

The Latin vae victis is rendered guai ai vinti (woe to the vanquished).[3][14] The noun guaio, “trouble”, was drawn from the interjection taken as a plural, and gave in turn inguaiare (1950).[11]

Timeline

  • c. 1224 – First record, in Saint Francis of Assisi.[7][8][5]
  • 13th century – The noun guaio is drawn from the interjection.[11]
  • 1950 – Inguaiare is recorded.[11]

Meanings

  3. (archaic) alas, a cry of grief.[7][2][3]

Usage notes

Guai is also the plural of the noun guaio “trouble, mess”, which Nocentini derives from the interjection.[11][14][15]
