Root Explanation

Orthoclase is formed from "ortho-" (from Greek "orthos", meaning straight or correct) and "klasis" (from Greek "klasis", meaning breaking). The word refers to a mineral that cleaves in a straight direction, hence its name meaning 'correct cleavage'.

Memory Tip

Think of 'straight' ('ortho-') and 'breaking' ('klasis') to remember that orthoclase refers to a mineral that breaks in a straight line.
