In short: Once the standard singular pronoun, 'thou' vanished from everyday English by the 17th century. While most European languages retained a distinction between formal and informal address, English shifted toward a universal 'you,' leaving 'thou' to survive only in religious prayer, regional dialects, and the occasional literary flourish.

The word 'thou' traces back to the Proto-Indo-European *tu, a root shared by languages ranging from Hindi to Latin. In Old English, 'thou' served as the singular counterpart to the plural 'ye.' However, beginning in the 1300s, the English language began adopting a 'T-V distinction'—a social convention influenced by French, where plural pronouns were used to address superiors or strangers as a mark of respect.

By the 17th century, the use of 'thou' in standard English fell into steep decline. Linguists suggest this was driven by the rise of a new middle class and the increasing association of 'you' with polite society. Because 'thou' could signal either intimacy or contempt—depending on whether it was used for a friend or an inferior—'you' became the safer, more neutral default. By 1650, 'thou' had largely disappeared from everyday speech in southern Britain, though it persisted in pockets like the West Midlands and among the Society of Friends.

The loss of this distinction has left modern speakers with a limited toolkit for expressing social nuance. While Shakespeare used 'thou' to signal power dynamics or deep emotional bonds, modern English relies on context to convey those same shifts. Today, 'thou' survives primarily as a marker of solemnity in religious prayer, where it is used to maintain a sense of reverence, or in specific regional dialects in northern England, where it remains a living part of local speech.
