Etymology

The word "dosage" originates from the French dosage, derived from dose (a measured portion) + -age (a suffix forming nouns). "Dose" itself traces back to Greek dosis (a giving, portion), from didonai (to give). The suffix -age was adopted from Old French, often denoting an action or its result. Thus, "dosage" logically evolved to mean "the measured giving" or "result of administering a dose."
