All three of these are Old English pronouns and are no longer in use. With that said, Thee, Thou, and Thine (or Thy) are all 2nd person pronouns. Thee is the 2nd Person nominative, Thou is the 2nd Person Objective, and Thine/Thy are the 2nd Person Possessives. The most common places to see these in use nowadays would be in works of Shakespeare, so I will pull some examples from his prose in order to show these pronouns in usage. Thee: Shakespearean Example: "... by being ignorant of what greatness is promised thee." Modern Translation: "... by not knowing what greatness is promised to you." Thou: Shakespearean example: "O Romeo, Romeo, wherefore art thou Romeo?" Modern Translation: "Oh Romeo, Romeo, Why are you Romeo?" (in the context she is distraught that her lover turned out to be Romeo of the rival family.) Thy/Thine: Shakespearean Example: "Deny thy father and refuse thy name;" Modern translation: "Deny your father and refuse your name;" (or more simply "leave your family so that you can be with me") Hope this helps :)

These are forms of the second person singular pronoun which is no longer used in modern standard English which now uses "you" for the singular and plural.; * thou - the subject of the sentence - you * thee - the object - you * thine - the possessive - yours I understand there are some parts of Scotland where these forms are still used but otherwise you will only find these forms in religious works such as early English translations of the Bible. I am sure others will have greater insight into these forms so you will probably get a few answers to your question.

They are the archaic forms of 'you' and 'your'. This is the full pronoun declension alongside the grammatically equivalent forms for 'I': Thou/I Thee/me Thy/my Thine/mine So, as you can see 'thou' means 'you' when it's the subject and 'thee' means 'you' when it's the object (like me, him, us, them). 'Thy' means 'your' and 'thine' means yours.

And when you get more familiar with German, try replacing the "th" in thou, thee and thine with "d" and notice the similarity between the German equivalents: du, dich and dein!

And of course, you will find these forms in the works of Shakespeare!
