Thee

The word thou is a second person singular pronoun in English. It is now largely archaic, having been replaced in almost all contexts by you. It is used in parts of Northern England and by Scots (/ðu/). Thou is the nominative form; the oblique/objective form is thee (functioning as both accusative and dative), and the possessive is thy or thine. When thou is the grammatical subject of a finite verb in the indicative mood, the verb form typically ends in -(e)st (e.g., "thou goest"; "thou do(e)st"), but in some cases just -t (e.g., "thou art"; "thou shalt"), although in some dialects of Old English (mainly in the North), this verb form ended in -s, hence the Quaker habit of using what looks like the third person form of the verb with "thee" as the subject (paralleling the usage of "you"). In Middle English, thou was sometimes abbreviated by putting a small "u" over the letter thorn: þͧ.

Originally, thou was simply the singular counterpart to the plural pronoun ye, derived from an ancient Indo-European root. Following the Norman invasion of 1066, thou was used to express intimacy, familiarity or even disrespect, while another pronoun, you, the oblique/objective form of ye, was used for formal circumstances (see T–V distinction). In the 17th century, thou fell into disuse in the standard language, oft regarded as impolite, but persisted, sometimes in an altered form, in regional dialects of England and Scotland, as well as in the language of such religious groups as the Society of Friends. The use of the pronoun is also still present in poetry.
