Etymology
The word 'adviser' is built upon the verb 'advise', which entered Middle English from Old French 'aviser', meaning "to consider, view". This French term derived from the Vulgar Latin 'advisare', a frequentative form of Latin 'advidere', meaning "to look at, consider". The core Latin components are 'ad-' (toward) and 'videre' (to see), suggesting the original sense was "to look at or consider a matter". The agent suffix '-er', of Germanic origin, was added to form a noun denoting "one who does this action". Thus, an adviser is literally "one who helps others to see or consider a situation clearly".
