History for bisect

When you bisect something you are cutting it in two. The word bisect itself will tell you that if you know Latin. The word was formed in English, but it came from two Latin elements. The bi- came from a Latin prefix meaning “two.” The -sect came from a Latin verb secare meaning “to cut.”
