Although “thy” may seem odd, it is an Old English word with a true definition listed in the dictionary. Interested in learning more? Read on to discover our complete guide on the term “thy.”

What Is the Definition of Thy?

According to the Collins Dictionary, “thy” (ðaɪ) is an old-fashioned, religious or poetic word for “your” when speaking to another individual. It is the possessive form of “thou” and is used to show possession. 

The prefix thy is used only when addressing one person — especially God — in a personal capacity. For example, “though shalt love the Lord, thy God, with all thy heart.”

What Is the Etymology of Thy?

According to the American Heritage Dictionary of the English Language, our word of the day comes from the Middle English variant of “thin” or “thine” which derives from Old English thīn tu- in Indo-European roots.  

Note: Thyn (Old English), thyne (Middle English), and thine (current spelling) are all “your.”

Like the word “thy,” you might see thou in Shakespeare’s plays such as Romeo and Juliet. Just look at this famous quote: “Wherefore art thou Romeo?” 

Are There Any Other Old English Pronouns?

In Modern English, there are really only four pronouns that are frequently used to address a person or persons: you, your, yourself, and yours. 

In contrast, Old English used ten pronouns:

  • Thou — Used to address a person of inferior status, such as a servant or child. Also used to address a friend, to impart a poetic ring when expressing profound thoughts, or when reciting a prayer. 
  • Thee — Like thou, thee is used when addressing a person of inferior status, to impart a poetic ring, or to recite a prayer. 
  • Thy — Used similarly to thou and thee; however, thy is not used before words beginning with a vowel or before words that start with a silent “h” followed by a vowel. Instead, the word “thine” is used. 
  • Thyself — Used similarly to thou, thee, and thy.
  • Thine — Used to show possession without a following noun as well as with a following noun starting with a vowel or a silent “h” followed by a vowel. 
  • Ye — Used to address one or several people of exalted social position(s). 
  • You, Your, Yourself, Yours — Used in the same way that they are used today.
