The letter M is derived from the Phoenician Mem, via the Greek Mu (Μ,μ). Semitic Mem is most likely derived from a " Proto-Sinaitic" ( Bronze Age) adoption of the "water" ideogram in Egyptian writing. The Egyptian sign had the acrophonic value /n/, from the Egyptian word for "water", nt; the adoption as the Semitic letter for /m/ was presumably also on acrophonic grounds, from the Semitic word for "water", *mā(y)-.
