'dismisser' originates from the verb 'dismiss', which comes from Latin, specifically the word 'dimittere', where 'dis-' meant 'apart' and 'mittere' meant 'send'.

'dimittere' transformed into the Old French word 'desmisser', and eventually became the modern English word 'dismiss' through Middle English.

Initially, it meant 'to send away', but over time it evolved into its current meaning of 'to reject or refuse'.
