the.com/trapper

means A person who catches animals (historically for fur) using traps rather than active pursuit, letting a baited device do the hunting.

from Simply 'trap' plus the agent suffix '-er' — 'trap' itself traces back to Old English 'treppan/træppe', related to words meaning to tread or step, since early traps were often pits or snares meant to catch a foot. The word entered its most famous chapter with the North American fur trade, when 'trapper' came to mean the men who ran trap lines for beaver and other pelts across the wilderness — a usage so dominant it's the one most people picture first.
