Forms
þū[1] Late West Saxon accusative þē, genitive þīn, dative þē; dual ġit, plural ġē.[2] Anglian texts and poetry have the accusative þeċ (Northumbrian also ðeh), beside þē.[3][4] Unstressed, it must have had a variant with a short vowel.[2] It is written þū or ðū, and can be joined to a preceding verb, as in westū and scealtū.[5][4]
Etymology
It is inherited from Proto-Germanic *þū (“thou”), from Proto-Indo-European *túh₂.[1] It is the Indo-European pronoun of the second person singular, the same word as Gothic 𐌸𐌿 (þu), Old Norse þú, Old Frisian thū, Old Saxon thū, Old Dutch thū and Old High German dū.[6][7] Outside Germanic, Orel lists Latin tū, Ancient Greek σύ (sú), Old Irish tú and Lithuanian tù among its relatives.[8] Kroonen reconstructs the nominative as *tuH and suggests that its form may owe something to the plural Proto-Germanic *jūz.[6] Köbler gives the variant Proto-Indo-European *tū̆ beside it.[7]
Hogg and Fulk reconstruct the late Proto-Germanic singular as *þu, accusative *þek, genitive *þīnō, dative *þiz; unlike the first-person pronoun, the nominative and the oblique cases come from one stem.[9] The accusative goes back to *twe, the nominative with an added *-e, which lost its /w/ in unstressed use and then took a final *-k as in the first person.[9]
Earliest recorded meaning
The pronoun is first recorded in the Vespasian Psalter, whose Old English gloss was added in the mid-ninth century.[10][11] In Psalm 2 the gloss reads sunu min ðu earð ic to dege ic cende ðec “thou art my son, today I have begotten thee”, over Latin “filius meus es tu ego hodie genui te”, with the Anglian accusative ðec.[11][3]
Semantic evolution
The pronoun is used on its own, reflexively in the dative or accusative (ne ondrǣd þū þē “do not fear”), and strengthened with self or āna “alone”.[4] In glosses it renders Latin “tu”.[7] In Beowulf the spelling þū occurs 43 times and ðū 19 times.[5]
The word lived on as Middle English thou, the subject form used to someone of lower rank as well as to God or a lord, and is English thou.[12][13]
Timeline

- 890×897 – Þu leofusta broður “thou dearest brother” in the Pastoral Care (Hatton 20).[14][11]
- s. x/xi – þū and ðū over sixty times in the Beowulf manuscript.[15][5]
