The word "转折点" is formed by sequentially combining three characters: 转, meaning "to turn" or "change direction"; 折, meaning "to bend" or "break", here contributing to the sense of a shift or transition; and 点, meaning "point". The combination creates a literal compound where 转折 together denotes a change or turn, and 点 specifies it as a precise moment or location, resulting in the term for "turning point".
