Pronunciation

Forms

dēop (comparative dēopra, superlative dēopost)[1] Noun: dēop n., genitive singular dēopes, beside dȳp n. and a feminine dȳpe.[2][3][4] The spelling dīop occurs for both the adjective and the noun, for example Dióp seáð in the Kentish Glosses.[5][6]

Etymology

It is inherited from Proto-West Germanic *deup, from Proto-Germanic *deupaz (“deep”).[1][7] The adjective is found in all the old Germanic languages: Gothic 𐌳𐌹𐌿𐍀𐍃 (diups), Old Norse djúpr, Old Frisian diāp, Old Saxon diop and Old High German tiof.[7][8][4] Heidermanns lists it among the primary adjectives of Germanic.[9] The noun, “depth, the deep”, is the adjective used as a neuter noun, and Köbler sets up a Proto-Germanic neuter *deupą (“depth”) for it, with parallel neuter nouns in Old Norse and Old Frisian.[4][10]

Outside Germanic, Kroonen and Orel compare Old Irish domain (“deep”), Welsh dwfn (“deep”) and Lithuanian dubùs (“hollow, deep”), which point to a root Proto-Indo-European *dʰewbʰ-.[7][8] Köbler gives the root as *dʰeub- (“deep, hollow”), after Pokorny.[4] How the Germanic adjective was formed from it is not settled: Kroonen thinks it may have been made to a strong verb, a variant of Proto-Germanic *dūbaną (“to dive”), or that it continues a pre-Germanic formation in -nó- whose consonants were changed by Kluge's law.[7][1] The verbs dyppan (“to dip”) and dīepan (“to deepen”) belong to the same family.[4]

Proto-Germanic /eu/ appears in Old English as ⟨ēo⟩, as in this word beside the ⟨iu⟩ of the Gothic form.[11]

Earliest recorded meaning

The adjective is first recorded in King Alfred's translation of the Pastoral Care, in the Hatton manuscript of 890×897: “se wisa Salomon sæde ðætte suiðe deop pol wære gewered on ðæs wisan monnes mode”, “the wise Solomon said that a very deep pool was dammed up in the mind of the wise man”.[12][13] The noun appears in the annal for 897 of the Parker Chronicle, whose manuscript was begun about 900: “Þreo asæton on ða healfe þæs deopes ðe ða Deniscan scipu aseten wæron”, “three ran aground on the side of the deep channel where the Danish ships had run aground”.[14][13][6]

Semantic evolution

In its literal sense the adjective describes wells, pits, water and floods: in Genesis the Flood stands fifteen ells deep over the hills.[2] It had a wide range of figurative senses: deep wounds and deep crimes, a profound error, a “stern” judgement and the “awful” day of Doom, and a solemn oath or message, often rendering Latin “profundus”, “gravis” and “solemnis”.[2][15] In the laws it means “heavy, severe”: deopum ceape “at a high price”, a deope friðsocne “an inviolable sanctuary”, and the adverb deope of harsh punishment and atonement.[16][6] A homily calls an epistle swiðe deop “very deep” to hear, that is hard to understand.[6] The noun names the deep, the abyss and the sea, chiefly in poetry and the metrical Psalms, and in a gloss it renders Latin “fretum” “strait”.[2][6] The poet of Andreas uses it for the deep sea.[17]

Both lived on in Middle English dep: the adjective of pits, ditches and water, and the noun of deep water, the sea and the bottom of the sea.[18] The word is now English deep.[19]
