Ilaryo is a modern, stylistic variant of Ilario/Hilario, ultimately rooted in the Latin Hilarius, itself from Greek hilaros ‘cheerful, merry, gracious.’ The core stem hilar- traveled widely through Christian Europe, producing local forms while retaining the upbeat meaning. Ilaryo keeps the sunny sense but updates the look with a contemporary y, giving it an international feel.

Usage reaches back to late antiquity via Saint Hilarius of Poitiers and the desert monk Saint Hilarion, whose cults seeded Romance (Ilario in Italian; Hilario in Spanish and Portuguese) and Eastern forms (Hilarion/Ilarion in Greek, Ukrainian, and Russian). Additional variants include Hilaryo in Filipino contexts, Latin Hilarius, and feminine or unisex counterparts such as Ilaria, Hilária, and Hilary. Diminutives like Lari or Lario appear in Italian.
