'consonant' originates from Latin, specifically the word 'consonare,' where 'con-' meant 'together' and 'sonare' meant 'to sound.'

'consonare' transformed into the Old French word 'consonant,' and eventually became the modern English word 'consonant' through Middle English.

Initially, it meant 'sounding together,' but over time it evolved into its current meaning of 'a speech sound that is not a vowel.'
