Etymology

The word equator comes from the Latin root aequus meaning 'equal', because it names the invisible line that makes the top and bottom of the Earth the same. So, the equator is the line around the middle of the Earth that divides it into two 'equal' parts, and the country Ecuador is named after this line.
