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

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

Initially, it meant 'to warn or remind someone,' but over time it evolved into its current meaning of 'an official order to appear in court.'
