amplification
The act of making something louder, stronger, or bigger.
Amplification means making something bigger, stronger, or louder. When you use a microphone and speakers to amplify your voice, you're making it loud enough to fill an auditorium. Without amplification, an electric guitar sounds quiet and thin, but plug it into an amplifier and suddenly it can shake the walls.
Scientists use amplification when they need to study something tiny: they might amplify a DNA sample to create millions of copies they can actually examine. Teachers practice amplification when they take a simple idea and expand it with examples and details to help students understand better.
In everyday conversation, amplification can mean strengthening an effect that's already there. Social media can amplify a message by spreading it to thousands of people instantly. A rumor gets amplified as it passes from person to person, often growing larger and more distorted along the way. When you amplify something, you're not creating it from nothing; you're taking what already exists and making it more powerful or noticeable. A small problem at school might get amplified into a bigger conflict if people keep talking about it and adding their own feelings to the situation.
