What does rostrum mean?
A rostrum is principally a formal platform from which a person speaks to an audience, as in a parliament, courtroom, assembly, or ceremonial hall. The word has a somewhat grand, institutional tone and suggests a speaker whose words carry particular authority, whether or not the platform itself is physically imposing. In zoological and anatomical contexts, a rostrum is a beak or a beak-shaped projection, as in the snout of certain animals or fish. In older nautical language, it can also denote the projecting bow or prow of a ship. These related meanings all reflect the word’s Latin origin, in which rostrum referred to a beak or beak-like projection. Today, the speaking-platform sense is the most familiar in formal public and political settings, while the other senses occur chiefly in specialized or historical writing.
A raised platform or stand from which a person addresses an audience, especially in a formal assembly or ceremonial setting.
"The president approached the rostrum to deliver the opening address."
Formal and institutional; common in descriptions of parliamentary, legal, and ceremonial proceedings.
A beak, beak-like projection, or snout, especially of an animal.
"The bird used its narrow rostrum to probe the mud for food."
A specialized zoological or anatomical term.
The projecting bow or prow of a ship, especially in historical nautical usage.
"The ship’s carved rostrum was visible above the waves."
Chiefly historical or specialist.
“Rostra” is the traditional Latinized plural and is especially used for the individual platforms in an assembly.
"Several members rose from their seats and addressed the assembly from the rostra."
From the Latin word for “beak,” the rostrum literally became the place where a speaker's words projected outward.

Etymology of rostrum
The English word comes from Latin rostrum, meaning “beak” or “beak-shaped projection,” and by extension the prow of a ship, whose front resembles a beak. Its use for a platform from which a person speaks developed by analogy with the projecting beak or mouth of a speaker. The modern English sense is therefore a metaphorical extension of the original Latin meaning, while the zoological and nautical senses preserve older, more literal associations.
