plaustrum

plaustrum uit.-lat.

Uncertain; possibly from Latin plautus~plōtus (“flat, broad”), thus "flatwagon", or Latin plaudere~plōdere (“clap, clatter”), thus "clatterer", both from Proto-Indo-European *pleh₂- and containing *-trom (“tool-suffix”). V. Bertoldi considers it a substrate word of various forms, among which ploxenum (“wagon-box”). C.f also Latin plaumorātum (plauromātum?) (“a type of plough”) and Proto-Germanic *plōgaz (“plough”) of likewise uncertain etymology.
