What does deadfall mean?
A deadfall is a primitive but effective animal trap built from a heavy object — typically a log, slab of stone, or weighted box — that is propped up at an angle and held in place by a delicate trigger arrangement supporting a bait. When an animal nudges the bait, the support gives way and the weight falls, killing or pinning the animal. The term predates modern steel traps and remains standard vocabulary in hunting, trapping, and wilderness-survival contexts. Separately, especially in North American forestry and ecology, deadfall refers to dead wood lying on the forest floor: trees and limbs brought down by wind, age, or disease. This second sense carries no negative connotation; ecologists value deadfall as crucial habitat for insects, fungi, and small animals. The two meanings share the transparent logic of their formation — simply "dead" plus "fall" — making the word easy to remember once its senses are known.
A heavy weight, such as a log or stone, propped up so that it falls on and traps or kills an animal when the bait is disturbed.
"He built a deadfall from a flat rock and a figure-four trigger to catch rabbits."
Most often encountered in historical, hunting, and survival literature.
Fallen dead trees and branches lying on the ground, considered collectively.
"The forest floor was littered with deadfall left over from last winter's storms."
Especially common in North American forestry and ecological writing.
Regular plural; used both for multiple traps and, less commonly, for scattered pieces of dead timber.
"Early fur trappers set dozens of deadfalls along the river each season."
Before steel traps existed, hunters killed game by balancing hundreds of pounds of log on a few sticks — one nudge of the bait, and gravity did the rest.

Etymology of deadfall
Deadfall is a straightforward English compound formed from "dead" (Old English dēad) and "fall" (Old English feallan), literally describing either the fatal fall of the trap's weight or the fallen state of dead timber. The compound arose in English in the early modern period, with the trapping sense well established by the seventeenth century among hunters and fur traders. Both components are native Germanic words, so the word has cognates across the Germanic languages rather than Romance-language relatives.

How deadfall is actually used
The trapping sense is somewhat traditional and appears most often in discussions of hunting, survival skills, and historical practice; the forestry sense is common in North American usage, particularly in ecological and land-management contexts.
Easily confused with deadfall
A pitfall is a trap consisting of a concealed pit (or figuratively a hidden danger), whereas a deadfall uses a falling weight to kill or trap.
