Glaives, also known as polearms, are weapons with long shafts and blades attached to the end. However, there are several synonyms for this particular word, including voulges, halberds, bills, pikes, and spears. Voulges are similar to glaives but have a curved blade instead of a straight one. Halberds have both an axe blade and a spike, making them more versatile. Bills are also similar to halberds but have a straight blade instead. Pikes are long and pointed, used for thrusting and poking opponents from afar. Lastly, spears have a pointed blade attached to the end of a long shaft, often used for hunting or in battle. Despite their differences, all of these weapons fall under the category of polearms.
