Etymology

It is inherited from Middle High German ouch, inherited from Old High German ouh, inherited from Proto-Germanic *auk.[2][1][3] The same particle is Gothic 𐌰𐌿𐌺 (auk, “for, but, also”), Old Norse auk, Old English ēac, Old Frisian āk and Old Saxon ōk,[2][4] and it survives as Dutch ook, archaic English eke, Swedish och (“and”) and Danish og (“and”).[5][1]

Its origin is disputed, and perhaps particles of separate origin fell together, as the different senses suggest: the Gothic word could also mean “for” and the Old High German one “but”.[2][5][6] One explanation takes it as an imperative “add!” of the strong verb Proto-Germanic *aukaną (“to add, increase”) (in 𐌰𐌿𐌺𐌰𐌽 (aukan) and Old Norse auka), from Proto-Indo-European *h₂ewg- (“to increase”), the root of Latin augeō.[2][7] Kluge favours it because of Old English þǣr-tō-ēacen (“besides”), literally “added to it”, and the Grimms already saw in the word the idea of something added.[2][8]

The other explanation joins a particle Proto-Indo-European *au, as in Ancient Greek αὖ (aû, “again, on the other hand”), with the emphatic particle Proto-Indo-European *ǵe.[2][9] Kroonen and Orel accept only this, Kroonen as Proto-Indo-European *h₂eu-ǵe;[4][9] Pfeifer also thinks it very likely, comparing Latin aut (“or”), Sanskrit उ (u, “and, also”) and Tocharian A ok, Tocharian B uk (“still”), and allows that the word was later attached to the verbs of increase.[5] The Duden dictionary takes it as a mixture of a frozen case form and an old particle.[10]

Earliest recorded meaning

Old High German ouh is recorded from the second half of the 8th century, in glosses and the Abrogans, and then in Isidor, Tatian, Otfrid and Notker.[3][11] Its senses ranged from “also, likewise, moreover, even, namely” to “on the other hand, but”.[3][12]

Semantic evolution

The contrasting sense “but”, still found in the older stages, was lost, and the adding sense prevailed.[5][7] In Middle High German ouch joined a new sentence to the last, set it against it or confirmed it.[13] Modern German uses auch as an adverb (“also, besides, even”) and as a modal particle expressing annoyance, confirmation or doubt; with interrogative words it generalises (was auch geschieht “whatever happens”) and with wenn it concedes (wenn auch “even if”).[10][3] In the phrase sowohl … als auch “both … and” it was already described by Adelung.[14]

Timeline

  • After 765 – Old High German ouh appears in glosses.[11]
  • 1060–1065 – Middle High German ouch is used in Williram's commentary on the Song of Songs.[15]
  • 1793 – Adelung describes auch as a conjunction marking an addition.[14]
