Etymology

It is borrowed from Latin cum (“with”),[2][3][4] related to the prefix com-,[2] abstracted from Latin phrases such as cum privilegio, with privilege (1589 in English use).[2][3]

Earliest recorded meaning

As part of Latin phrases used in English: 1589;[3][2] the SOED records it from late Middle English in the names of combined parishes, such as Chorlton-cum-Hardy.[5]

Semantic evolution

As an English preposition joining two nouns, as in a kitchen-cum-dining room, it is from about 1869–71.[4][2] Latin phrases with cum in English include cum laude, with praise, and cum grano salis, with a grain of salt.[6]

Usage notes

The vulgar slang cum, to ejaculate or semen, is a different word: a variant spelling of come in its sexual sense, recorded by 1973 and apparently from pornographic writing; it has no connection with the Latin preposition.[7]
