I just learned about anorthic crystals in my geology class.

That's interesting! What does that mean exactly?

It means they have three unequal axes that meet at an angle.

Oh, so they're not symmetrical like most crystals. Got it!

Root Explanation

Anorthic is formed from the prefix "an-" (meaning not) and the root "orthos" (from Greek, meaning straight or correct). The word describes something that is not straight or correct, often used in a geological context to refer to certain types of rocks.

Memory Tip

Think of 'not' ('an-') and 'straight' ('orthos') to remember that 'anorthic' refers to something that is not straight or correct.
