Primogenitor → It is formed from "primus" (meaning first) and "genitor" (meaning one who begets or produces). The word "primogenitor" refers to the first ancestor or the first parent in a lineage.
Think of 'first' ('primus') and 'one who produces' ('genitor') to remember that a primogenitor is the first ancestor or parent in a family line.
