The kanji 阻阻 is a phono-semantic compound (形声文字 - keisei moji). The left side is 阜（こざとへん - kozatohen), which is the radical for "hill" or "mound," indicating an area of land with a raised height. The right side is 且, which serves as the phonetic component, indicating the sound of the kanji, while also having the meaning of "moreover" or "and." Together, these components create the meaning of "to hinder" or "to block," implying a barrier or obstacle in the terrain, such as a hill or a steep slope, which impedes movement or progress. This obstacle acts as a blockage.
