Characterized by or showing eager, intense, and sometimes greedy enthusiasm or desire.
From Latin 'avidus' (eager, greedy) + English suffix '-ious' (full of), creating an adjective form that emphasizes the intense quality of the desire.
This is an archaic or rare variant of 'avid'—while 'avidious' adds an extra syllable and sounds more formal, it actually fell out of fashion because plain 'avid' is shorter and clearer.
