The kanji 捺 is a phono-semantic compound (形声文字, keisei moji). The left side is the radical 手 (て, te), meaning "hand" or "action involving the hand." The right side is 奈 (nai), which functions phonetically here, indicating the pronunciation. Therefore, the kanji's structure suggests an action of the hand related to pressing or stamping something, aligning with its meaning.
