phon-, phono-, -phone, -phonia, -phonic, -phonetic, -phonous, -phonically, -phonetically, -phony +
(Greek: sound, voice, speech, tone)
This phono-, phon- should not be confused with another phono-, phon- that means "slaughter, murder, homicide". In Greek, a distinction is made between the phonos (PHOH nohs), "murder", which is spelled with the Greek letter omicron in the last syllable; and the Greek phonos (phoh NOHS), "voice", which is spelled with the letter omega in the last syllable. Both omicron and omega became the letter "o" in English.
