'you' originates from Old English, specifically the word 'ēow', where it was used as a dative and accusative form of 'gē', meaning 'you' (plural).

'ēow' transformed into the Middle English word 'you', and eventually became the modern English word 'you'.

Initially, it meant 'you' in a plural sense, but over time it evolved to be used for both singular and plural forms.
