lance
For tagging purposes, a lance specifically refers to a style of spear popularly recognized from jousting, which has a distinct and large cone for its head. The cone can be as long as, or even longer, than the actual haft. Lances are a popular symbol for a knight.
Not to be confused with "lances" in Fire Emblem games, which improperly use the term to refer to any kind of spear.
