[4] However, m is also used as an abbreviation for mile. [5] 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)-. [2] Use in writing systems Archaic M was used in ancient Roman texts to abbreviate the personal name 'Manius' (A regular capital M was used for the more common personal name 'Marcus') [11] The Roman numeral M represents the number 1000, though it was not used in Roman times. There is, however, scant evidence that the letter was later introduced in the early centuries A.D. by the Romans. [3]
