In grammar, a diminutive is a word having a special affix which conveys the idea of littleness, and all other ideas connected with this, as tenderness, affection, contempt, etc. The opposite of diminutive is augmentative. In Latin, diminutives almost always ended in lus, la, or lum; as Tulliola, meum corculum, little Tullia, my dear or little heart; homunculus, a manikin. The Italian is particularly rich in diminutives and augmentatives, such compound diminutives as fratellinucciettinetto (a diminutive of frate, brother) being sometimes employed. Among English diminutive affixes are kin, as in manikin, a little man: pipkin, a little pipe: ling, as in gosling, a little goose; darling, that is, dearling, or little dear; and et, as in pocket, from poke, a bag or pouch; tablet, a little table. Diminutives are also formed, in colloquial and familiar language, by adding y or ie to the names, as Charley, Mousie, etc. Research Diminutive
