Word Nuance & Usage

Historically, 'thou' was the informal and familiar singular subject pronoun (like French 'tu'), whereas 'ye' and 'you' were plural or formal; today, however, 'thou' is often mistakenly perceived as formal because of its survival in religious and classical texts. Grammatically, 'thou' is strictly a subject pronoun (as in 'thou art'), while 'thee' is the corresponding object pronoun.
