History

Etymology

From Japanese 無 (mu, “nothing, neither yes nor no”).

Coined by Charles Étienne Brasseur de Bourbourg in 1864 (through mistranslating a word in the Mayan Madrid Codex using the De Landa alphabet), as the name of a land that had been submerged by a catastrophe; later identified as Atlantis by Augustus Le Plongeon.

Borrowed from Burmese မူး (mu:).

From Ancient Greek μῦ (mû), derived from Phoenician 𐤌𐤌 (mm /⁠mem⁠/, “water”). Doublet of mem.

From Mandarin 畝/亩 (mǔ).

Borrowed from Greek μ (m).
