Chairmanship → It is formed from "chair" (from Old French *chaiere*, meaning a seat or throne) and "-manship" (from Old English *-scipe*, meaning the state or condition of being). The word "chairmanship" refers to the state of being in charge or presiding over a meeting or organization, as indicated by the term 'chair'.
Think of a 'chair' as a position of authority and 'manship' as the condition of holding that position — that's why chairmanship means the role of leading or presiding.
