Thou vs. Though — What's the Difference?

Another point to consider is the realm of literature and historical writings. "Thou" is prevalent in classical literature, especially in religious texts and old poetry. You'll find it frequently in Shakespeare's works or the King James Bible. On the opposite side, "Though" remains constant in both historical and contemporary writings. Its function as a contrasting conjunction has kept it relevant in various forms of writing across the ages.

Lastly, while "Thou" has a clear grammatical role as a pronoun, "Though" is multifaceted. Besides being a conjunction, "Though" can be an adverb, typically at the end of a sentence, indicating a concession like, "I did it anyway, though."

It's also interesting to note that "Thou" has seen a decline in colloquial usage. As language evolved, the distinction between the formal "you" and informal "Thou" became less pronounced in English, leading to "Thou" becoming largely obsolete. However, "Though" retains its value in everyday conversation, bridging sentences and ideas that may stand in opposition to each other.

"Thou" hails from older English and once served as the singular, informal form of "you." When someone used "Thou," they were addressing another in a familiar or colloquial manner, similar to how "tu" is used in some Romance languages. On the other hand, "Though" is a conjunction used in modern English. It often indicates contrast, introducing a statement that differs from or contrasts with a previous statement. For instance, one might say, "It was raining, though we still went for a walk."
