'office-supportive' is a compound word formed from 'office' and 'supportive', where 'office' refers to a place of work and 'supportive' means providing assistance.

The term 'supportive' evolved from the Middle English 'supporten', which came from the Old French 'supporter', and eventually became the modern English 'supportive'.

Initially, 'supportive' meant 'to bear or hold up', but over time it evolved to mean 'providing assistance or encouragement'.
