History

Etymology

Onomatopoeic. Compare um.

Attested since 1808. In typography, the em is named after the em quadrat (later called em quad), from m quadrat, a metal type used in letterpress typesetting, which is as wide as the point size of the font.

From Russian эм (em), Ukrainian ем (em), etc.

See 'em.

Coined by Christine M. Elverson by removing the "th" from them, perhaps influenced by the pre-existing em/'em, now often perceived as apheretic forms of them (though originally unrelated).
