Bannister → The word 'bannister' originates from the Middle English 'banistere', which is derived from the Old French 'bannière' (meaning a banner or flag) and 'est' (meaning a support or structure). The term originally referred to a support for a banner, which evolved to mean the handrail of a staircase. Thus, a bannister is a support structure for people using stairs.
Imagine a 'banner' ('bannière') that supports you as you go up or down the stairs — that's what a bannister does, it supports you on the staircase.
