Makaius is a recent American coinage that blends Makai, a Hawaiian word meaning "toward the sea", with the Latin-sounding ending of names like Kaius and Cassius. It has no traditional meaning of its own, but parents who choose it usually have the "toward the sea" sense of Makai in mind. The name has appeared only sporadically in US statistics, with fewer than ten births in most years, before it jumped to number 2246 with 63 boys in 2025.
