'inarticulation' originates from Latin, specifically the word 'inarticulatus,' where 'in-' meant 'not' and 'articulatus' meant 'distinctly spoken.'

'inarticulatus' transformed into the French word 'inarticulé,' and eventually became the modern English word 'inarticulation' through Middle English.

Initially, it meant 'not distinctly spoken,' but over time it evolved into its current meaning of 'lack of clarity or coherence in speech or expression.'
