Thy Vs Thine

Thy vs Thine: A Comparison

The English language has undergone numerous changes over the centuries, and one of the most notable changes has been the use of second-person pronouns. In Old English, there were two second-person singular pronouns – “thu” and “ye.” While “ye” is no longer used, its modern equivalent, “you,” has remained in use. However, the use of “thu” has evolved into two distinct forms: “thy” and “thine.” This article aims to examine the differences between “thy” and “thine” and how they are used in modern English.


“Thy” is a possessive adjective that is used before a noun to indicate ownership. In other words, it is the equivalent of “your” in modern English. Usage of “thy” was popular in Middle English and in early Modern English. Here are a few examples:

– “Thy mother is a great cook.”
– “Can I borrow thy book?”
– “Thy shirt is torn.”

Note: Thy is used before a word beginning with a consonant.

“Thee” and “Thou” were the subjective and objective case of “thu.” “Thy” was used before words beginning with a consonant, and “thine” was used before vowels. In general, we don’t use the word “thy” anymore because it’s considered outdated. But, it still exists in the Bible as well as in a few literary works.


“Thine” is another possessive adjective that also means “your.” However, it is only used before a word that begins with a vowel. It is still used in modern English, but it’s not as common as “thy.” Here are a few examples:

– “That car is thine.”
– “May I borrow thine umbrella?”
– “The diamond ring is thine.”

Note: Thine is used before a word beginning with a vowel.

In summary, “thy” is used before a word beginning with a consonant, and “thine” is used before a word beginning with a vowel. Both are used, albeit uncommonly, to mean “your.”

FAQs About Thy vs Thine:

Why are “thy” and “thine” no longer commonly used?
The use of “thy” and “thine” declined when the Middle English language evolved to Modern English. In Modern English, we only use “your” which is quite flexible, and can be used before any word regardless of its starting letter. This makes these older, more rigid forms of the same word feel archaic.

Are “thy” and “thine” interchangeable?
No, they are not interchangeable. “Thy” is used before a word beginning with a consonant, and “thine” is used before a word beginning with a vowel.

When should I use “thy” and “thine”?
You can use “thy” when the noun you want to use it with starts with a consonant, and use “thine” when the noun starts with a vowel.

Is there any difference in meaning between “thy” and “thine”?
No, there is no difference in meanings between the two words, and they are both used to mean “your.”

Final Thoughts

While “thy” and “thine” are not commonly used in modern English, they remain relevant in historical texts and can add a certain charm to one’s writing. Understanding their meanings and use can provide a deeper understanding of the evolution of the English language. Nonetheless, when it comes to communication, using “your” is far more effective and clearer to any reader. Remember, the main thing is always to be clear and concise.
