'dejected' originates from Latin, specifically the word 'deiectus,' where 'de-' meant 'down' and 'iacere' meant 'to throw.'

'deiectus' transformed into the Old French word 'dejecter,' and eventually became the modern English word 'dejected' through Middle English.

Initially, it meant 'to throw down,' but over time it evolved into its current meaning of 'feeling sad or disheartened.'
