"Come and drink."
Translation:आओ और पियो ।
Hindi has three forms of 'you' - तू , तुम and आप in increasing order of formality. Therefore, the imperative can take three forms depending on which of these is the implied subject - आ and पी with तू, आओ and पियो with तुम, आइए and पीजिए with आप.
For example, you'd say आओ और पियो when talking to a friend and आइए और पीजिए when talking to a stranger.
