thou

thumb|Most modern English speakers encounter "thou" predominantly in the works of William Shakespeare|Shakespeare; in the works of other Renaissance, medieval and early modern writers; and in the [[King James Bible or Douay-Rheims Bible.]]

The word thou () is a second-person singular pronoun in English. It is now largely archaic, having been replaced in most contexts by the word you, although it remains in use in parts of Northern England and in Scots ( ). Thou is the nominative form; the oblique/objective form is thee (functioning as both accusative and dative); the possessive is thy (adjective) or thine (as an adjective before a vowel or as a possessive pronoun); and the reflexive is thyself. 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").
