Etymology

Origin of vertical

First recorded in 1550–60; from Latin verticālis, equivalent to vertic- (stem of vertex ) vertex + -ālis -al ¹

Explanation

Vertical describes something that rises straight up from a horizontal line or plane. A telephone pole or a tree can usually be described as vertical in relation to the ground. The walls of your house — unless there's some terrible problem — are vertical. They rise straight up from the foundation, at a ninety degree angle. When you're standing up, you're vertical, as opposed to when you lie down in a horizontal position on the couch. The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, "v," which points down.
