to elapse or pass
⏳ 推移 = 推 push + 移 shift; time and situations get pushed along, shifting onward
推 means to push, 移 means to shift or move. Together they describe time being pushed forward (elapsing) or a situation shifting and developing over time. The two pushing-and-shifting characters reinforce the sense of gradual onward change.
推 — hand radical 扌 + 隹 (short-tailed bird)
A semantic-phonetic compound: the hand radical 扌 gives the meaning 'to push' or act with the hand, while 隹 supplies the sound (originally close to 'tui'). The core sense has stayed remarkably stable, expanding from physical pushing to figurative uses like 'recommend' or 'infer'.
移 — grain 禾 + many 多
Originally a semantic-phonetic compound: 禾 (grain) gives the meaning and 多 (duō) suggested the sound in Old Chinese. It first referred to transplanting rice seedlings, then broadened to mean 'to move, shift, or relocate' in general.
