The word "gisarme" is a term that is often used in medieval contexts to describe a type of polearm weapon that incorporates both an axe blade and a spear tip. The term is derived from the Old French word "guisarme," which means "war-axe," and there are several synonyms that can be used to describe this type of weapon. Some alternative terms that are commonly used include the voulge, the halberd, the billhook, and the glaive. These terms can be used interchangeably to describe weapons that share similar characteristics with the gisarme, and they are often used in historical discussions and reenactments to provide more precise descriptions of weapons and combat techniques.
