multidimensional

Etymology

It is formed from English multi- + dimensional,^[1][2][3] or, as Etymonline analyses it, from multi- with dimension and the suffix -al.^[4] The prefix comes from Latin multus (“much, many”),^[4] and the noun from Latin dīmēnsiō (“a measuring”), from dīmētior (“to measure out”).^[4] The OED compares earlier formations such as one-dimensional, two-dimensional and four-dimensional.^[1]

Earliest recorded meaning

In mathematics and science, of or relating to space of more than three dimensions: 1884, in the Gentleman's Magazine.^[1][4]

Semantic evolution

The word began as a technical term for space of more than three, occasionally more than two, dimensions.^[1][4] From 1946, in the Political Science Quarterly, it was used generally of anything having many aspects or components,^[1] a use the OED connects with the earlier non-technical use of multidimensionality, itself recorded from 1906.^[1] Collins now gives this general sense first.^[5]
