In a manner showing excessive desire for food, money, or possessions; eagerly and without restraint.
From the adjective 'greedy' with the adverbial suffix '-ly' added, which transforms adjectives into adverbs describing how an action is performed.
The suffix '-ly' turns any adjective into an adverb, which is why English has paired words like 'quick/quickly' and 'sad/sadly'—it's one of our language's most productive shortcuts.
