注视
zhù shì · HSK 5
to watch attentively
👀 注 (pour/focus) + 视 (see) = pour your seeing onto something
注 means to pour or concentrate (as in 注意 attention); 视 means to look or see (as in 视力 eyesight). Together: to pour your gaze — i.e. watch attentively or stare fixedly.
注 — water 氵 + master 主 (phonetic)
A semantic-phonetic compound: 氵 (water) gives the meaning of pouring or flowing, while 主 supplies the sound. The original sense was 'to pour water in,' which extended to 'concentrate, focus' (as in pouring attention) and 'to annotate' (pouring explanation into a text).
