In English it's not based on context, it's based on word order. Declension is a cool concept but it's far more confusing to foreigners because word order basically doesn't matter. For example in Czech: Jan zabil Petra Jan Petra zabil Petra Jan zabil Petra zabil Jan Zabil Petra Jan and Zabil Jan Petra are all equivalent to the English "John killed Peter." Change Jan to Jana and Petra to Petr and all 6 of those become "Peter killed John." Even more confusing to a foreigner learning it is that Petra and Jana are the feminine forms of those names in the nominative case.
