The word "截取" is formed by combining the character "截", which means to cut off or intercept and is itself composed of the radical "戈" suggesting cutting action and the phonetic component "隹", with the character "取", meaning to take or obtain and composed of "耳" (ear) and "又" (hand) depicting the act of taking. Together, they create a verb meaning to intercept and take, specifically referring to extracting a portion from a whole, as in capturing a segment of information.
