Monoaxial

Part of speech: adjective

Definitions

1. Having, or moving along, just one axis of rotation or direction in space, with no others involved

Etymology: Monoaxial is a plain technical compound: "mono-", from Greek "monos" meaning "single" or "alone", joined to "axial", the adjective from "axis". Together they describe something that has or turns about only one axis. The word is used in engineering and science to describe devices, mechanisms or motions constrained to rotate or move along a single line, as opposed to biaxial or triaxial arrangements with two or three. The "axis" part traces back to Latin "axis", meaning an axle or pivot, which is also the source of the English noun. Because "axial" is simply the adjectival form, "monoaxial" is a modern construction built from classical parts rather than a word that developed naturally over centuries.
