没法儿

Can't
🚫 没 (not have) + 法 (way) + 儿 = no way to do it
没法 literally means 'no method/way,' and the 儿 suffix is a Beijing-style ending. Together it expresses 'there's no way' or 'can't be done.' Compare with 办法 (way/method) — 没法儿 is the negative colloquial form.
没 — water 氵 + 殳 (hand with weapon)
Originally depicted something sinking or being submerged in water, combining the water radical 氵 with 殳, suggesting a hand reaching into a whirlpool. The core sense was 'to sink, drown, disappear under water.' From there it extended to 'to vanish, not have,' giving the modern negative meaning 'not, have not.'
法 — water 氵 + go 去
Originally written 灋, combining the water radical 氵 (suggesting a level standard, like water finding its level), the mythical beast 廌 (which judged guilt), and 去 (to remove or banish). The 廌 was later dropped, leaving 法. The core meaning evolved from 'law' or 'standard' to also include 'method' and 'way of doing'.
