1 Extremely hungry.
1.1 (of hunger or need) very great; voracious.
Late Middle English: from Old French ravineus, from raviner ‘to ravage’ (see raven).
The crow stood its ground in the ravine next to the carcass and the wolf which had secured their lunch. Crow was patient, though hungry. The wolf was clearly ravenous, and naturally got first dibs.
[Today’s ODO offer was the archaic word “ravin“, but archaic terms have raised concern for their usefulness in modern conversation. As luck would have it, the more familiar ravenous has not been used here before, and it looks like it has some common roots with ravin, bringing it along to more modern use…just a bit.]
