Usage note Insignia, originally the plural of Latin insigne, began to be used as a singular in the 18th century, and the plural insignias appeared shortly thereafter. All uses—insignia as a singular or plural and insignias as a plural—are fully standard. The singular insigne still occurs, but insignia is more common.
