Onin as a Baby Name. Meaning and Origin of Onin

What is the meaning of the name Onin ?

The baby name Onin is a Male name , 2 syllables long and is pronounced OH-nin (/ˈoʊnɪn/) — alternative pronunciation: oh-NEEN (/oʊˈniːn/).

Onin is Basque in Origin.

Onin is a rare given name with several plausible roots. In Japanese, it corresponds to Ōnin (応仁), the medieval era name best known from the Ōnin War; the characters mean “responsive benevolence.” As a personal name it is unusual in Japan, but the macron is often dropped in Romanization, yielding Onin. Elsewhere, the name also functions as a streamlined variant or nickname of Ronin (“masterless samurai”), and some modern parents adopt it for its clean two-syllable sound.

Usage is scattered in late 20th- and early 21st-century records, notably in the Philippines, where Onin appears both as a standalone name and as a clipped nickname formed by dropping an initial consonant (e.g., from Ronin or other -nin names). Variants and related forms include Ōnin and the stress-marked Onín; Ronin is a related term rather than a direct equivalent. Meaning depends on origin, from “responsive benevolence” to the ronin sense.
