The kanji 沿 is a phono-semantic compound (形声文字, けいせいもじ). The semantic component is 氵 (water, さんずい, さんずい) which indicates the meaning of water or liquid. The phonetic component is 㕣 which provides the sound of the kanji. The original form depicts water flowing along a bank or shoreline, thus acquiring its meaning "along" or "following".
