The kanji 侵侵 is a phono-semantic compound (形声文字). It is composed of the semantic component 亻 (nin-ben, meaning "person") and the phonetic component 侵 (shin), which lends the sound. Originally, 侵 likely depicted someone approaching or infiltrating something, with the "person" radical emphasizing the human agency involved in the act. The phonetic component 侵 helped in the pronunciation.
