insigne

Insigne is a term used for a sign, badge, or emblem that identifies rank, office, membership, or achievement. In English, insignia is the standard plural form; insigne is the singular form mainly encountered in historical, heraldic, or specialized contexts.

The word derives from Latin insigne meaning a mark or sign, from insignire to mark, from signum sign. The concept appears across cultures and languages in various forms, from official seals to heraldic devices, and it encompasses both decorative and functional elements.

Insignia appear in military, law enforcement, civil service, and fraternal or religious orders. They may be metal badges, embroidered patches, miniature pins, or heraldic devices, and are typically worn on uniforms, sashes, collars, or displayed on banners. Ceremonial insignia often incorporate symbols such as stars, crosses, or coats of arms to indicate rank, office, or affiliation.

In heraldry, the insigne refers to the device or emblem displayed on a shield or banner. In modern usage, corporate insignia denotes logos and symbols representing an organization. The design and possession of insignia serve to communicate authority, membership, or achievement and are often involved in ceremonies marking promotions, appointments, or honors.
