Etymology

It is inherited from Middle English dimencioun, from Middle French dimension or directly borrowed from Latin dīmēnsiō (“a measuring”), dīmēnsiōnem,[2][3][4] from dīmētīrī, to measure out, from dis-, apart, and mētīrī, to measure (see measure),[2][3][5] from Proto-Indo-European *me-, to measure.[3]

Earliest recorded meaning

Measurement, size, measurable extent: before 1398, in Trevisa's translation of Bartholomaeus;[2] the late 14th century in Etymonline.[3]

Semantic evolution

In geometry a mode of linear measurement, such as length, breadth and thickness, is from 1413.[6] Bulk, size, extent or capacity is from the 1520s (1529),[3][6] and extension in time from 1605.[6] In algebra the degree of a product of quantities is from 1557.[6] The figurative sense, any aspect of a situation, is from 1929,[3][6][7] and a kind of realm or universe, as in Rod Serling's fifth dimension in The Twilight Zone (1959), came later.[3] The verb, to cut to size, is from 1754.[4]
