XIII. OF THE LETTER M.
The consonant M is a semivowel and a liquid, capable of an audible, humming sound through the nose, when the mouth is closed. It is heard in map, murmur, mammon. In the old words, compt, accompt, comptroller, (for count, account, controller,) the m is sounded as n. M before n, at the beginning of a word, is silent; as in Mnason, Mnemosyne, mnemonics.
