barricade

The word 'barricade' has a vividly literal origin in urban conflict. It entered English in the late 16th century from the French 'barricade', which itself derived from the French 'barrique', meaning 'barrel'. The semantic link is direct: during historical street fighting, especially the French Wars of Religion, the most readily available materials for hastily blocking a street were empty barrels filled with earth and stones. Thus, the object used for blocking—the barrel—gave its name to the act and structure of blocking itself. Over time, the meaning generalized from a barrier made specifically of barrels to any improvised defensive barrier, and the word also evolved from a noun into a verb describing the action of creating such an obstruction.

Structure: barric (barrel) + ade (noun/verb suffix) barric (from French 'barrique', meaning 'barrel', of uncertain origin, possibly from Spanish 'barrica'); ade (a suffix forming nouns and verbs, from Latin '-ata', via French '-ade').
