thine

Extracted from the Wikipedia article Thou.
The word thou () is a second-personsingularpronoun in English. It is now largely archaic, having been replaced in most contexts by the word you, although it remains in use in certain traditional dialects of Northern England and Scotland (also pronounced or today). 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").
