* "Thou" is the nominative case and is used as the subject of a sentence. For example:
* "Thou art my friend." (You are my friend.)
* "Thee" is the objective case and is used as the object of a verb or preposition. For example:
* "I see thee." (I see you.)
* "Give it to thee." (Give it to you.)
It's important to remember:
* Old English is not the same as Modern English. These pronouns are no longer used in everyday speech.
* "Thee" and "thou" were originally used in a more formal and respectful way. They were often used when addressing someone of higher social status, or when speaking about God.
* "You" is the modern equivalent of both "thou" and "thee."
So, in summary, "thou" and "thee" were the second person singular pronouns in Old English, used as the subject and object of a sentence respectively.
