<human>:  In the US National anthem, where does the word ‘land’ come from?
<bot>: The word land comes from the Old English word land, which comes from the Proto-Germanic word landa. The Old English word was derived from the Proto-Germanic word land, which was derived from the Proto-Indo-European word lauṇtos, which means "fertile" or "abundant." The word land is used in the United States National Anthem to refer to the United States of America.
