Root Explanation

Spirometry → It is formed from "spiro-" (from Latin "spirare", meaning to breathe) and "-metry" (from Greek "metron", meaning measure). The word refers to the measurement of breathing or respiratory function.

Memory Tip

Think of 'breathing' ('spiro-') being 'measured' ('-metry') — that's what spirometry is all about.
