🍃 顺 follow/go-along + 应 respond = go along and respond to conditions, i.e. adapt
顺 means smooth or going-with, and 应 means to respond. Put together, 顺应 is responding by going along with whatever comes, so it lands on comply, conform, adapt to.
顺 — 川 (river) + 页 (head/face)
顺 combines 川 (flowing river) with 页 (head), originally depicting a head turned to follow the flow of water. The image of going along with the current gave rise to meanings like 'to follow,' 'smooth,' and 'in order.' It remains tied to ideas of compliance and natural sequence.
应 — 广 (shelter) + 心 (heart) + 隹 (bird)
Originally written 應, this character combined a phonetic component with 心 (heart) to suggest 'responding from the heart' or 'answering a call'. The simplified form 应 keeps the top portion. Over time it broadened from 'respond/answer' to also mean 'should' or 'ought to'.
