Etymology
the word 'teaspoonful' is a transparent english compound formed in the modern era. its first element, 'teaspoon', emerged in the 17th century, combining 'tea', a loanword from chinese via dutch, with 'spoon', a common germanic utensil term from old english. the second element, the suffix '-ful', descends directly from old english '-full', an adjective-forming suffix meaning 'full of', which was later nominalized to denote a specific quantity. the logic of the word is entirely literal and practical: it names the precise volume that fills a teaspoon, a standardized unit of measurement in both culinary and medical contexts.
