I just read about a mineral called amphibole in my geology class.

Oh really? What makes it interesting?

It's part of a group of silicate minerals, and they have such complex structures.

That sounds cool! I love learning about different minerals.

Synonyms & Antonyms

Root Explanation

Amphibole → It is formed from "amphi-" (meaning both or on both sides) and "bole" (from Greek "ballein", meaning to throw). The word refers to a mineral that can occur in different forms, thus representing the idea of being on both sides or having dual characteristics.

Memory Tip

Think of 'both sides' ('amphi-') and 'throwing' ('ballein') to remember that 'amphibole' refers to a mineral that can take on different forms.
