Final answer:
A hermit is a person who lives in solitude and does not fit the definitions given. A heretic is someone who challenges official belief systems, and hermetic refers to being sealed-off or isolated.
Step-by-step explanation:
While engaging in reading Hamlet or any other complex literary work, practicing looking up diction can greatly enhance comprehension and insight into the text's deeper meanings. In the context of the given definitions, hermit is not accurately described by either of the definitions provided. A hermit is instead someone who lives in solitude, often for religious reasons. In comparison, a heretic is indeed someone who goes against the official teachings of a particular belief system, which could be a relevant term if discussing religious characters or themes within literature. On the other hand, hermetic refers to something that is completely sealed off, which could relate to themes of isolation or separation within a story.
