Pronunciation

Etymology

It is formed from English sub- + group.[2][3][4][5][6] The OED compares French sous-groupe, recorded from 1819 or earlier.[2] Group itself is from French groupe, from Italian gruppo (“group, knot”), probably of Germanic origin.[3][2]

Earliest recorded meaning

A subordinate group, a subdivision of a group: 1826, in the Edinburgh Journal of Science.[2][4] Etymonline dates it to 1825, as a term of classification,[3] and Dictionary.com to 1835–45.[6]

Semantic evolution

The word began in classification, for a group within a larger group.[3][2] From 1854 it was also a verb, to divide into subgroups.[2][4] In mathematics, from 1881, a subgroup is a group whose elements all belong to a larger group and are combined by the same operations.[2][5][7]
