divisional

The word 'divisional' is built upon the noun 'division', which entered English from Old French division, itself from Latin divisionem. The Latin source, dividere, meant to force apart or separate, composed of 'dis-' (apart) and the root related to finding a way or cleaving. The suffix '-al' is a prolific adjective-forming element from Latin, attaching to nouns to mean 'of or pertaining to'. Thus, 'divisional' literally means 'pertaining to the act or result of separating', which evolved in modern organizational and military contexts to describe units created by subdividing a larger whole.

Structure: division (act of dividing) + al (adjective suffix) - division: From Latin division-, divisio (a dividing), from the verb dividere (to force apart, to divide). The root 'vid' relates to separating. - al: A suffix forming adjectives, from Latin -alis.
