A rostrum is a small platform that is often used for public speaking. It is usually raised up and has a microphone or other equipment to help the speaker be heard. Rostrums can be found in many places such as schools, auditoriums, conference rooms, and even outdoors during rallies or protests. So, if you are at a formal event and you see a raised platform for a speaker, it's likely a rostrum!
