The Great Passage opens with an evocative shot of a ferris wheel suspended over a great sea, an expanse the narrator describes as the “vast ocean of words.” Our thoughts are imperfect instruments with no inherent vessel, and so our natural state is to be stranded on islands of misunderstanding. Words give our meaning form, and allow our thoughts to connect across this sea. And dictionaries are the ships that cross it, offering clear and sturdy definitions to master the tides.
