An old-fashioned word for "your" — the possessive form of "thou" (the old word for "you" when talking to one person). You will not hear this in normal speech today. You meet it in three places: the Bible ("Honour thy father and thy mother"), Shakespeare and other old poetry, and hymns or prayers.

An old-fashioned word for "your"一個表示「your（你的）」的古老說法 — the possessive form of "thou""thou"的所有格形式 (the old word for "you" when talking to one person古時候對一個人說話時用的「you」). You你 will not hear this in normal speech today今天正常說話不會聽到這個字. You你 meet it in three places會在三個地方遇到它: the Bible ("Honour thy father and thy mother")聖經（如「Honour thy father and thy mother」）, Shakespeare and other old poetry莎士比亞和其他古詩, and和 hymns or prayers聖歌或禱告詞.

There is a small rule that goes with it, the same rule as "a" and "an": "thy" comes before a word starting with a consonant sound (thy book, thy hand), and "thine" comes before a vowel sound (thine eyes, thine own heart). "Thine" also works alone, the way "yours" does: "This book is thine." One thing that surprises people: "thou" and "thy" were once the WARM, close words, used to family, children, close friends, and God — while "you" was the polite, distant word for a stranger or a superior.

There is有 a small rule一個小規則 that goes with it跟著它, the same rule as "a" and "an"跟「a」和「an」一樣: "thy""thy" comes before出現在...前面 a word starting with a consonant sound以子音開頭的字 (thy book, thy handthy book、thy hand), and而 "thine""thine" comes before出現在...前面 a vowel sound以母音開頭的字 (thine eyes, thine own heartthine eyes、thine own heart). "Thine""Thine" also works alone也可以單獨用, the way "yours" does就像「yours」那樣: "This book is thine.""This book is thine."（這本書是你的。） One thing that surprises people有件事讓人意外: "thou" and "thy""thou"和"thy" were once曾經是 the WARM, close words溫暖、親近的用詞, used to family, children, close friends, and God用在家人、小孩、好朋友和上帝身上——while而 "you""you"是 the polite, distant word客氣、有距離感的用詞 for a stranger or a superior用來對陌生人或長輩.

So when the Bible says "thy," it is not being grand and formal; it is being intimate. English later dropped the whole warm form and kept only the polite one, which is why "thy" now sounds grand to us — exactly backwards from what it meant.

So所以 when the Bible says "thy,"聖經裡說「thy」的時候, it它 is not being grand and formal不是要顯得高尚正式; it它 is being intimate而是親密. English後來的英語 later dropped捨棄了 the whole warm form整個溫暖的用法, and而 kept只保留了 only the polite one客氣的那一種, which is why所以 "thy""thy" now sounds grand to us現在聽起來反而高尚——exactly backwards from what it meant跟它原本的意思完全相反.

Modern writers sometimes use it on purpose to sound ancient or holy, and jokey signs and fantasy games use it for flavour, often getting the grammar wrong.

Modern writers現代作家 sometimes有時 use it on purpose故意使用它 to sound ancient or holy為了聽起來古老或神聖, and而 jokey signs and fantasy games搞笑招牌和奇幻遊戲 use it for flavour用它增添一點味道, often常常 getting the grammar wrong把文法用錯.
