M is the thirteenth letter of the English Alphabet, and a labial articulation, formed by a compression of the lips. It is called a semi-vowel, as the articulation or compression of the lips is accompanied with a humming sound through the nose, which constitutes a difference between this letter and b. Its sound is uniform; as in man, timeM is a numeral letter, and among the ancients stood for a thousand; a use which is retained by the moderns. With a dash or stroke over it, it stands for a thousand times a thousand, or a million. As an abbreviation, M stands for Marcus, Martius, Manlius or Mutius. M M.A. or A.M. stands for artium magister, master of arts; M.D. for medicinoe doctor, doctor of medicine; A.M. for anno mundi, the year of the world; MS, for manuscript; MSS, for manuscripts. In astronomical tables, M stands for meridian, meridional, or mid- day. M.A. In medical prescriptions, M stands for maniple, or handful, or misce, mix, or mixtura, a mixture. IV/.A.
