'cohort' originates from Latin, specifically the word 'cohors,' where 'co-' meant 'together' and 'hortus' meant 'garden or enclosure.'

'cohors' transformed into the Old French word 'cohorte,' and eventually became the modern English word 'cohort' through Middle English.

Initially, it meant 'an enclosure or garden,' but over time it evolved into its current meaning of 'a group or company.'
