Vertical

"Vertical" refers to a direction that is straight up and down, perpendicular to the ground. It's often used to describe something aligned along this up-and-down line. For example, a vertical line runs directly from the top of a structure to its base. In business, “vertical” can also mean a specific industry or market segment, such as the healthcare vertical or the finance vertical, focusing on particular types of products or services catered to that sector. Essentially, “vertical” denotes an orientation or specialization along a straight, upright line or within a specific industry niche.
