派别
pài bié · HSK 7
faction
派 (faction) + 别 (distinction) = a distinct faction, school, or group
派 — water radical 氵 + 𠂢 (branching stream)
派 originally depicted branching tributaries of a river, with 氵 (water) added to reinforce the meaning. The right side 𠂢 shows a stream splitting into smaller channels. From 'river branch' it extended to mean a faction, school, or to dispatch/send out.
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).
