Commands to someone you call टू tu just use the verb stem
–बैठ baith,
बोल bol,
जा ja,
आ aa,
कह kah,
खा kha,
कर kar.
दे de
.ले Ie.
पि pi.
As their shortness suggests, these टू tu commands are very blunt (or, if you prefer, sharp!) - 'Speak!' 'Sit!'; used out of context, they could easily give offence. Care needed here!
