没意思

boring
🥱 没意思 = 没 not-have + 意思 meaning/interest = no interest, dull
没 means not-have (negation); 意思 means meaning or interest. Stack them and you get having no interest, which is exactly what boring describes. The same 没 starts many no-something phrases in Mandarin.
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.'
