Thee is an archaic form of the word "you," used primarily in English literature and historical texts. It is a second-person singular pronoun, often associated with a more formal or poetic style of communication. Thee is commonly found in works by authors such as William Shakespeare and John Milton, reflecting the language of earlier centuries.
In modern usage, thee is rarely employed in everyday conversation, but it can still be encountered in religious texts, such as the King James Bible, where it is used to convey reverence. Thee is part of a broader set of pronouns that include thou and thy, which also denote singular address.
