遏制
è zhì · HSK 7
to keep within limits
🛑✋ è zhì sounds like edge-stop — holding something back at the edge
遏 (è) means to block or restrain, 制 (zhì) means to control or regulate. Together they form a compound: block + control = to contain or hold in check, like stopping something before it crosses a limit.
制 — knife 刂 + 未 (tree branches)
Originally depicted a knife 刂 cutting branches from a tree, showing the act of trimming or shaping wood. From this concrete sense of cutting to size came the meanings 'to make,' 'to manufacture,' and by extension 'to control' or 'regulate' — shaping things to a desired form.
