'abdicant' originates from Latin, specifically the word 'abdicare,' where 'ab-' meant 'away' and 'dicare' meant 'to proclaim.'

'abdicare' transformed into the French word 'abdiquer,' and eventually became the modern English word 'abdicant' through Middle English.

Initially, it meant 'to renounce or disown,' but over time it evolved into its current meaning of 'relating to abdication or a person who abdicates.'
