The Japanese conjunction '即ち (すなわち)' means 'namely' or 'in other words'. It is used to clarify or restate something that has been mentioned previously, often to provide a more precise or detailed explanation. This word is commonly used in both written and formal spoken Japanese. For example: He is my best friend, namely, my brother「彼は私の親友、即ち、私の兄です」(かれはわたしのしんゆう、すなわち、わたしのあにです). The solution is simple, namely, to work harder「解決策は簡単だ、即ち、もっと頑張ることだ」(かいけつさくはかんたんだ、すなわち、もっとがんばることだ).
