Part of speech: adjective

Definitions

1. Characterized by possessing a singular flat plane that defines its form
2. Involving a structure that consists of one level or flat surface without other elevations or complexities
3. Describes something constructed with or limited to only one flat plane defining its shape

Etymology: "Monoplanar" is a plain technical formation: the prefix "mono-", from Greek "monos" meaning "single" or "alone", joined to "planar", which describes anything relating to a plane. Put together, the word describes something that has or lies in just one plane, such as a flat, two-dimensional arrangement in geometry or a structure built on a single level. The second element carries most of the meaning. "Planar" derives from Latin "planus", meaning "flat" or "level", the same root that gives English "plane" in the sense of a level surface. The prefix simply narrows that flatness to a single one, which is why the word is used in fields like geometry, engineering, and optics, where a configuration is described by whether all its parts fall within one flat surface.
