Learned borrowing from Latin rōstrum (“beak, snout”), from rōd(ō) (“gnaw”) + -trum, from Proto-Indo-European *Hreh₃d- + *-trom. The pulpit sense is a back-formation from the name of the Roman Rōstra, the platforms in the Forum where politicians made speeches. The Rōstra were decorated with (and named for) the beaks (prows) of ships from naval victories.
rostrum (plural rostra or rostrums)
From rōd(ō) (“to gnaw”) + -trum, from Proto-Indo-European *Hreh₃d- + *-trom. Originally a bird's beak or animal's snout, but later extended to objects with a similar shape.
