cavalcader

A literary verb meaning to ride at a gallop, or more broadly to move about in a noisy, boisterous group — les enfants cavalcadaient dans le jardin. Related to cavalcade (a procession of riders); mostly found in descriptive, literary writing.

• Les cavaliers cavalcadaient à travers la plaine. — The riders galloped across the plain.
• Les enfants cavalcadaient bruyamment dans les couloirs. — The children were charging noisily through the hallways.
• On entendait les chevaux cavalcader au loin. — You could hear the horses galloping in the distance.

Cavalcader has a literary, slightly old-fashioned flavor — in ordinary spoken French, galoper (for horses) or courir bruyamment (for boisterous kids) is what a native speaker would actually say.
