vertically

Vertically is the adverb form of the adjective vertical, indicating movement, orientation, or alignment along the vertical axis—up or down—and used to distinguish this direction from horizontal (side to side).

In geometry and physics, the vertical axis is perpendicular to the horizontal plane. A vertical line has undefined slope in standard Cartesian coordinates. Vertical distance measures height along the direction of gravity, and vertical coordinates are commonly denoted by y in many conventions.

Common uses include describing layout and alignment in design, architecture, and user interfaces, where elements may be stacked or scrolled vertically. In photography and film, vertical orientation (portrait mode) captures a tall, up‑and‑down composition. In everyday language, vertically often conveys an upright or ascent-oriented direction.

Etymology: vertically derives from the adjective vertical, which comes from Latin verticalis, related to the broader notion of height and orientation.

Related concepts include vertical and horizontal orientation, the vertical axis, altitude, and alignment.
