Did English ever have a formal version of "you"? (2011)
Summary: In Early Modern English, "thou" was the singular form and "you" was the plural form. Over time, the plural "you" became a polite form of address, eventually displacing the singular "thou" altogether. This change explains the peculiarity of traditional Quaker speech, which insisted on addressing everyone as "thou" to avoid distinctions of rank. Today, "thou" is perceived as archaic and formal, while its original intent was to be more informal.
