'''M''' (minuscule: '''m''') is the thirteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of several Western European languages and others worldwide. Its name in English is ''em'' (pronounced {{IPAc-en|'|ɛ|m|audio=LL-Q1860 (eng)-Flame, not lame-M.wav}}), plural ''ems''.<ref>"M" ''Oxford English Dictionary,'' 2nd edition (1989); ''Merriam-Webster's Third New International Dictionary of the English Language, Unabridged'' (1993); "em," op. cit.</ref>

==History== {| class="wikitable" ! Egyptian hieroglyph<br/>"n" ! Phoenician<br/>Mem ! Western Greek<br/>Mu ! Etruscan<br/>M ! Latin<br/>M |--- align=center |<hiero>n</hiero> | class=skin-invert-image|25x25px | class=skin-invert-image|35px | class=skin-invert-image|25px | class=skin-invert-image|x30px|Latin M |} The letter M is derived from the Phoenician Mem via the Greek Mu (Μ,&nbsp;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 {{IPA|/n/}}, from the Egyptian word for "water", ''nt''; the adoption as the Semitic letter for {{IPA|/m/}} was presumably also on acrophonic grounds, from the Semitic word for "water", ''*mā(y)-''.<ref>See F. Simons, "Proto-Sinaitic — Progenitor of the Alphabet" ''Rosetta'' 9 (2011): Figure Two: "Representative selection of proto-Sinaitic characters with comparison to Egyptian hieroglyphs", (p. 38) Figure Three: "Chart of all early proto-Canaanite letters with comparison to proto-Sinaitic signs" (p. 39), Figure Four: "Representative selection of later proto-Canaanite letters with comparison to early proto-Canaanite and proto-Sinaitic signs" (p. 40).

===English=== In English, {{angbr|m}} represents the voiced bilabial nasal {{IPA|/m/}}.

The Oxford English Dictionary (first edition) says that {{angbr|m}} is sometimes a vowel, such as in words like ''spasm'' and in the suffix ''-ism''. In modern terminology, this is described as a syllabic consonant (IPA: {{IPA|/m̩/}}).

The digraph, "mn," when used in the beginning of words, such as mnemonic, is pronounced as /n/. This digraph is the only instance where the letter {{angbr|m}} is silent.

M is the fourteenth most frequently used letter in the English language.

===Other languages=== The letter {{angbr|m}} represents the voiced bilabial nasal {{IPA|/m/}} in the orthography of Latin as well as in those of many modern languages. In Spanish, final {{angbr|m}} is rare and mostly corresponds to {{IPA|/n/}}, with {{IPA|/m/}} being a foreign pronunciation applied only by some speakers in loanwords.

In Washo, lower-case {{angbr|m}} represents a voiced bilabial nasal {{IPA|/m/}}, while upper-case {{angbr|M}} represents a voiceless bilabial nasal {{IPA|/m̥/}}.

===Other systems=== In the International Phonetic Alphabet, {{angbr|m}} represents the voiced bilabial nasal {{IPA|/m/}}.
