What Onyx means

Onyx is a given name.

The naming story behind Onyx

Wikidata records Onyx as a unisex given name. The entity identifier is Q109986129, and the classification was checked on 2026-10-20. The spelling matches a source label or alias exactly, without removing accents or linking it to a name merely because the letters look similar.

A database classification is different from an etymological explanation, so those questions remain open in the short meaning.

A modern root explanation needs an additional naming or linguistic reference.
