Root Explanation

Teaspoonful is formed from "tea" (from the Chinese word "t'e" or "cha", meaning a beverage made by infusing dried leaves) and "spoon" (from Old English "spōn", meaning a utensil for eating or serving). The suffix "-ful" (meaning full of) indicates a quantity. Therefore, a teaspoonful refers to a quantity that fills a teaspoon with tea.

Memory Tip

Think of a 'spoon' that is 'full of' tea — that's what a teaspoonful means.
