History
The letter M represents the bilabial nasal consonant sound, IPA [m] in Classical languages as well as the modern languages. It derives its shape from the Greek Mu (Μ, μ). Semitic Mem originally pictured water, in all probability.
The Oxford English Dictionary (first edition) says that 'm' is sometimes a vowel in words like spasm and in the suffix -ism. In modern terminology this would be described as a syllabic consonant — IPA [m̩].
