==Usage==In standard English, you is both singular and plural; it always takes a verb form that originally marked the word as plural, (i.e. you are, in common with we are and they are). This was not always so. Early Modern English distinguished between the plural you and the singular thou. As in many other European languages, English at the time had a T-V distinction, which made the plural forms more respectful and deferential; they were used to address strangers and social superiors. This distinction ultimately led to familiar thou becoming obsolete in standard English, although this did not happen in other languages such as French. Because thou is now seen primarily in literary sources such as King James Bible (often directed to God, who is traditionally addressed in the familiar) or Shakespeare (often in dramatic dialogs, e.g. "Wherefore art thou Romeo?"), it is now widely perceived ahistorically as more formal, rather than familiar. - Source: Wikipedia
