Alvito's dictionary for Blackthorne

Alvito's dictionary for Blackthorne is a language-learning aid given to John Blackthorne by Father Alvito. Its significance lies not only in helping Blackthorne speak Japanese, but also in the religious and political dispute its transfer exposes: Alvito treats the gift as a chance to reach one soul, while Rodrigues sees it as an unnecessary advantage for an enemy who is already close to Toranaga.

The dictionary as practical aid

Rodrigues notices that Blackthorne has acquired the dictionary and is speaking like a Japanese person with remarkable speed. To Rodrigues, this makes the dictionary part of a troubling reversal: Blackthorne has regained his ship and money, gathered retainers, and become intimate with Toranaga. The book is one concrete source of help in that transformation, though Rodrigues doubts it alone can account for how quickly Blackthorne has adapted.

Alvito's decision

At Mishima, Rodrigues asks Father Alvito why he gave Blackthorne the dictionary and suggests that he should have delayed doing so. Alvito acknowledges that he could have withheld it, but explains that he believes Blackthorne might be converted. He frames the decision as an attempt to save one man and his soul, even as he regards Toranaga's political position as finished. The dictionary thus serves a purpose beyond instruction: Alvito uses practical assistance as an opening for religious persuasion.

Disputed consequences

Rodrigues's response reveals how differently the same gift reads to the two priests. He sees Blackthorne's growing fluency and influence as ominous, and fears that the dictionary has helped make the Englishman more capable within Toranaga's circle. Alvito, by contrast, accepts that he has helped Blackthorne because he considers the possibility of conversion worth pursuing. The dictionary becomes a small object at the intersection of language, political advantage, and missionary purpose.
