Cohort comes from Latin cohors (genitive cohortis) 'enclosure, company of soldiers, division of an army', from co- 'together' + a root meaning 'enclosed yard' (related to hortus 'garden'). The historical trail runs through cohors in Latin and hortus in Latin. Morphologically, cohort is transparent: it draws on Latin cohors (genitive cohortis) 'enclosure, company of soldiers, division of an army', from co- 'together' + a root meaning 'enclosed yard' (related to hortus 'garden'). Used as a noun, cohort now means "a group sharing a common feature, especially a statistical or age band", so the present definition can be read against the older forms and meanings. The same lexical family is also visible in related forms such as court and cohortative. The result is a borrowed or transmitted form whose modern spelling carries a compact record of its route into English.
