avidly

The adverb 'avidly' is built upon its adjectival base 'avid', which traces its lineage directly to the Latin avidus, meaning "eager, greedy, or longing for." This Latin term itself derives from the verb avere, "to desire or crave," a root that also flows into related English words like 'avidity'. The suffix '-ly' is of Germanic origin, a staple in English for converting adjectives into adverbs, indicating manner. Thus, the literal construction "in an eager manner" perfectly captures the modern abstract meaning of performing an action with intense enthusiasm or keen desire.

Structure: avid (eager) + ly (adverb suffix) - avid: From Latin avidus (eager, greedy), from avere (to desire, crave). Functions as the core adjective root. - ly: From Old English -līc (like, having the form of). A productive suffix forming adverbs from adjectives.
