What it means: A visual presentation showing how something works.

The part people get wrong

Watch for an unstressed vowel that is hard to hear.

Same family: demonstrate, demonstrative, demonstrably, demonstrator, demonstrated. If you can spell one, the shared part carries to the others.

Where it comes from: “Demonstration” comes from Latin *demonstrare*, meaning “to point out, show clearly.” Over time, it kept both senses in English: a clear proof or showing of something, and a public protest where people “show” their opinions together.
