dikey

Dikey is a Turkish adjective meaning vertical or upright. It is used to describe the orientation of objects, lines, and movements, or the position of elements relative to gravity. It contrasts with yatay, which means horizontal.

In science, engineering, architecture, and everyday language, dikey denotes vertical alignment, dimension, or movement. Common phrases include dikey eksen (vertical axis), dikey hareket (vertical movement), and dikey ölçüm (vertical measurement). In Turkish typography and information design, dikey text orientation is also described as dikey yazı, referring to writing that runs from top to bottom.

Etymology and usage notes: the term is a standard Turkish word derived from the root indicating uprightness, and it appears across educational, technical, and media contexts. It is typically used without quotation marks or specialized capitalization outside of titles or proper nouns. The natural opposite term is yatay, meaning horizontal, and the two are often paired in discussions of geometry, design, and spatial reasoning.
