Conversation

Have you ever thought about how everything is made up of tiny atoms?

Yeah, it's crazy to think that we're all just a bunch of atoms swirling around.

I read somewhere that even our thoughts are influenced by those atoms in our brains.

That makes sense! It's fascinating how such small things can have such a big impact.

Root Explanation

Atom → It is derived from the Greek word "atomos" (meaning indivisible), which is composed of "a-" (meaning not) and "tomos" (meaning to cut). The word "atom" refers to the smallest unit of matter that cannot be divided further.

Memory Tip

Think of 'not cutting' ('a-' means not and 'tomos' means to cut) to remember that an atom is something that cannot be divided any further.
