Here's a breakdown:
* Thou: Used as the subject of a sentence. Example: Thou art a good friend.
* Thee: Used as the object of a verb or preposition. Example: I love thee.
* Thy: Used as a possessive adjective. Example: Thy kindness is appreciated.
Here's an example of how "thee" was used in older English:
Modern English: I see you.
Older English: I see thee.
In modern English, we use "you" for both the subject and object of a sentence. So, "thee" is rarely used today.
It's important to note that "thee" was a familiar form of address, often used to refer to someone close to the speaker. The more formal and respectful form was "you."
