來自 you 的古體用法或詩意用法，來自古英語 thu,你，來自 Proto-Germanic*tu,你，來自 PIE*tu, 第二人稱單數(shù)人稱代詞，你，詞源同 thee,thine,thy.后由 you 所取代。

thou (pron.)

2nd nominative singular personal pronoun, Old English tu, from Proto-Germanic *thu (cognates: Old Frisian thu, Middle Dutch and Middle Low German du, Old High German and German du, Old Norse tu, Gothic tu), from PIE *tu-, second person singular pronoun (cognates: Latin tu, Irish tu, Welsh ti, Greek su, Lithuanian tu, Old Church Slavonic ty, Sanskrit twa-m).

Superseded in Middle English by plural form you (from a different root), but retained in certain dialects (e.g. early Quakers). The plural at first was used in addressing superior individuals, later also (to err on the side of propriety) strangers, and ultimately all equals. By c. 1450 the use of thou to address inferiors gave it a tinge of insult unless addressed by parents to children, or intimates to one another. Hence the verb meaning "to use 'thou' to a person" (mid-15c.).

Avaunt, caitiff, dost thou thou me! I am come of good kin, I tell thee! ["Hickscorner," c. 1530]
