Conversation

Have you ever heard of a coherer in early radio technology?

Yeah, I think it was one of the first devices to detect radio waves, right?

Exactly! It's fascinating how such a simple device worked so effectively.

I know, it’s amazing to think about how far technology has come since the days of the coherer.

Synonyms & Antonyms

Root Explanation

Coherer → It is formed from "co-" (meaning together) and "haerere" (meaning to stick or adhere). The word "coherer" refers to a device that causes particles to stick together, thus enabling the flow of electricity.

Memory Tip

Think of things 'sticking together' ('haerere') as a result of being 'with' ('co-') — that's why a coherer is a device that makes particles adhere together.
