Although I m-w'd "heritage" and "legacy", I still can't understand the difference between them.

If my father dies and leaves me a house, is this house my {quH} or my {'ISyar} ?

The earth which will be inherited by the poor, is a {quH} or a {'ISyar} ?

The culture of ancient rome, for the italians of today, is their {quH} or their {'ISyar} ?
