Read this: In December 1547, Francis was in Malacca (Malaysia) waiting to return to Goa (India) when he met a low-ranked samurai named Anjiro (possibly spelled "Yajiro"). Anjiro was not an intellectual, but he impressed Xavier because he took careful notes of everything he said in church. Xavier made the decision to go to Japan in part because this low-ranking samurai convinced him in Portuguese that the Japanese people were highly educated and eager to learn. They were hard workers and respectful of authority. In their laws and customs they were led by reason, and, should the Christian faith convince them of its truth, they would accept it en masse.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): In what language did Anjiro speak to Xavier?
Portuguese
