'pathetic' originates from Greek, specifically the word 'pathētikos', where 'pathos' meant 'suffering, feeling'.

'pathetic' changed from Greek 'pathētikos' into Late Latin 'patheticus' and Old French 'pathétique', and eventually became the modern English word 'pathetic' through Middle English.

Initially, it meant 'relating to suffering or strong feeling', but over time it evolved into its current meaning of 'evoking pity; miserably inadequate'.
