In plain English: Vertical means going straight up and down, like a line that stands upright rather than lying flat.
"The ladder is leaning against the vertical wall."
Usage: Use vertical to describe anything standing upright at a 90-degree angle to a flat surface, such as walls or poles. This term is often confused with "upright," but while both imply an upward orientation, vertical specifically emphasizes the straight alignment relative to gravity rather than just general posture.
The word entered English from Middle French and ultimately traces back to the Late Latin verticālis. It originally described something related to a vertex or top point before coming to mean standing upright.
