M. M in the Phoenician alphabet represented the wavy ap- pearance of water and was, in fact, called mem, “water,” in He- brew. In medieval times an M was branded on the brawn (fleshy part) of the left thumb of a person convicted of manslaughter. M is always pronounced in English, except in Greek words such as “mnemonics.” In Roman numerals the capital letter M stands for 1,000 (Latin, mille). |
