I am looking for the meanings to words like thou, thee, and thy. I see them in stories all the time and they confuse me a lot.
They are pronouns, in different forms, according to their grammatical role. Just like I, Me, My and Mine, and We, Us, Our and Ours, Middle and Early Modern English had these pronouns, only for the second person singular. Modern English and Middle and Early Modern English comparison: You - Thou: Thou shalt not kill (You shall not kill) You (like "Me") - Thee: Shall I compare thee to a summer's day? (Shall I compare you to a summer's day?) Your - Thy: Honor thy father and mother (Honor your father and mother) Yours - Thine: Thine be the glory (The glory is yours/shall be yours).
I hope you understand :)
