Rule reminder
A word family groups words that share the same root but differ in part of speech: verb, noun, adjective, adverb. Example family: LAVORO — lavorare (verb), lavoro (noun), lavoratore (agent noun), lavorativo (adjective), lavorativamente (adverb). Building word families improves vocabulary depth and enables you to use the right word in any grammatical context.
