'summon' originates from Latin, specifically the word 'summonere,' where 'sub-' meant 'under' and 'monere' meant 'to warn or advise.'

'summonere' transformed into the Old French word 'somoner,' and eventually became the modern English word 'summon' through Middle English.

Initially, it meant 'to warn or advise,' but over time it evolved into its current meaning of 'to call or bring someone or something to a place or into action.'
