Root Explanation

Oligoclase → It is formed from "oligo-" (from Greek "oligos", meaning few or little) and "clase" (from Greek "klasis", meaning breaking or fracture). The word refers to a mineral that has a few distinct cleavage planes, indicating its crystalline structure.

Memory Tip

Think of 'few' ('oligo-') and 'breaking' ('clase') to remember that oligoclase is a mineral with few distinct breakage patterns.
