insignia

Etymology

It is borrowed from Latin īnsignia (“badges, marks of office”),^{[2][3][4][5][6]} the plural of īnsigne (“mark, sign, badge of office”),^[2][6][7][8] the noun use of the neuter of the adjective īnsignis (“distinguished, marked”),^[2][6][5][9] formed from in- (“in, on”) and signum (“mark, sign”), the source of sign.^{[6][3][4][10]} The American Heritage Dictionary refers signum to the Indo-European root Proto-Indo-European *sekʷ-,^[6] while Ayto calls the origin of the Latin word uncertain.^[11] The same Latin word had come into English much earlier through French as ensign, recorded probably before 1400; after insignia arrived, ensign narrowed towards the sense of a flag.^[4][9][7] The OED also compares French insigne, recorded in the Académie dictionary of 1835.^[2]

Earliest recorded meaning

Badges or distinguishing marks of office or honour: 1648, in Mercurius Academicus.^[2][4][5] Etymonline dates it to the 1640s,^[3] Dictionary.com to 1640–50.^[12]

Semantic evolution

In Latin and at first in English the word was a plural, "badges, emblems".^[2][4] From 1774 it was also used as a singular, with a new plural insignias,^[2][4][12] and at about the same time the Latin singular insigne was taken into English (1773 in the OED, 1774 in Barnhart).^[2][4] From 1796 the word was used figuratively for marks or tokens of anything, as in "the insignia of mourning".^[2][12]

Usage notes

In Latin insignia is the plural of insigne, but in English it has long served as both singular and plural, and the plural insignias is also standard.^[15][12][5] The Latin singular insigne is still found but is less common,^[12][5] and the American Heritage Dictionary warns that it may strike readers as pedantic;^[15] Collins calls it rare.^[13]
