advisory

the word 'advisory' is built upon the verb 'advise', which entered english from old french aviser, itself derived from the vulgar latin advisare. this latin verb was a frequentative form of advisere ('to look at, consider'), a compound of ad- ('to') and visere ('to see'), the latter from the root vidēre ('to see'). the suffix -ory, of latin origin, is used to form adjectives denoting a function or purpose. thus, the literal construction 'serving for looking at/considering' evolved into the modern sense of 'having the function of giving considered counsel or warning'.

Structure: advis(e) + ory advis(e) - from latin advisare, a variant of advisere meaning 'to consider, look at', functioning as the core verb root. ory - from latin -orius, an adjective-forming suffix meaning 'relating to, serving for'.
