We give nothing so freely as advice, observed French writer Duc de La Rochefoucauld in 1665. "Hortative" and "exhort" (meaning "to urge earnestly") are two words that testify to our eagerness to counsel others. Both trace to Latin hortari, meaning "to urge." "Hortative" has been used as both a noun (meaning "an advisory comment") and an adjective since the 17th century, but the noun is now extremely rare. You may also encounter the adjectives "hortatory," "exhortatory," and "exhortative," all of which have the same meaning as "hortative."
