calc
Latinpebble, stone; to reckon
About This Root
From Latin calculus (small pebble), a diminutive of calx (limestone, lime). Romans did arithmetic by moving little pebbles on a counting board, so calculus came to mean 'reckoning.' This gives calculate, calculus (the branch of math), and calculating. Calcium comes from the same calx (lime) but keeps the mineral sense rather than the counting one.
