avid

The original and now relatively unfamiliar sense of avid, “desirous to the point of greed,” developed logically from its root in Latin, avēre (meaning “to long for”). It appears in such phrases as “avid of fame” and “avid for details,” expressions we are more likely to encounter in formal writing than in speech. More common today is the word’s somewhat weakened and ameliorated (that is, “made better,” or given a more positive connotation) meaning “extremely enthusiastic.” This is the sense regularly used of people who have embraced some hobby or pursuit (such as avid readers, gardeners, or knitters).
