深思
shēnsī · HSK 7
to ponder; to consider
🤔 深 = deep + 思 = think; literally deep-think, to ponder deeply
深 (shēn) means deep, the same character as in deep water. 思 (sī) means to think. Stacked together they mean to chew over something deeply or ruminate.
深 — water radical 氵 + 罙 (phonetic, depth)
深 combines the water radical 氵 with 罙, which depicts a hand reaching into a cave or hollow. Originally it described deep water, then broadened to mean 'deep' in any sense — distance, color, or feeling. The 氵 gives the meaning, while 罙 hints at both sound and the idea of reaching far in.
