Mannuss is Germanic in Origin.

Mannuss is a rare masculine name with Germanic roots. It most likely echoes the Latinized Mannus - recorded by Tacitus as the mythic ancestor of the Germanic peoples - linked to Proto‑Germanic *mann-, meaning “man, person,” and by extension “hero.” The spelling with double s reads as a modern Germanic-styled variant, stabilizing the final consonant and distinguishing it from Manus. In parallel, the Irish and Scottish Manus derives from Maghnus, itself from Old Norse/Latin Magnus, “great,” giving Mannuss a dual semantic field: “man” or “great,” depending on lineage.

Historical usage is sparse under this exact spelling, but cognates surface in classical texts (Mannus) and Gaelic records (Manus) from the late medieval period onward. Variants and related forms include Mannus, Manus, Magnus, Maghnus, Manne, and Manny/Mannie as diminutives. Today Mannuss suits families seeking a pan‑Germanic revival name with mythic resonance and a straightforward, strong meaning.
