Ensign (/ËÉnsÉn/; Late Middle English, from Old French enseigne ["mark", "symbol", "signal"; "flag", "standard", "pennant"], from Latin insignia [plural]) is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy.
As the junior officer in an infantry regiment was traditionally the carrier of the regimental colors, the rank acquired the name "ensign". This rank has generally been replaced in army ranks by second lieutenant. An ensign was generally the lowest-ranking commissioned officer, except where the rank of subaltern existed.
