Don't look at
🙈 别 (don't) + 看 (look) — a blunt command to avert your gaze
别 is the imperative negator used to tell someone not to do something. 看 means look or watch. Together they form a sharp prohibition: eyes off, now.
别 — separate (knife 刂 + 另 phonetic/'other')
别 originally depicted using a knife (刂) to separate flesh from bone, giving the core sense of 'divide' or 'part from'. The left component 另 ('another, other') reinforces the idea of setting things apart and also hints at the sound. From 'separate' the meaning naturally extended to 'other, different' and to the adverb 'don't' (i.e. do otherwise).
看 — hand 手 over eye 目
看 is an associative compound showing a hand (手, simplified to 龹) shading an eye (目), depicting someone shielding their eyes to look into the distance. From this concrete gesture it broadened to mean 'to look,' 'to watch,' and later 'to read' or 'to consider.'
