péi xùn bān · HSK 4
training class
🎓 培 cultivate + 训 train + 班 class = training class
培 (péi) means to cultivate or nurture, 训 (xùn) means to train or instruct, and 班 (bān) means a class or group. Together they name a short-term training course or workshop.
训 — speech radical 讠 (言) + river 川
A semantic-phonetic compound. The 讠 (speech) radical gives the meaning—words used to teach or instruct—while 川 (river) suggests the phonetic and the image of guiding flow. Together 训 means to instruct, admonish, or train, as in channeling someone with words.
班 — two jade 玨 + knife 刂 in the middle
班 originally depicted a knife (刂) dividing a pair of jade pieces (玨), showing the act of splitting jade between people. From this 'dividing' sense it came to mean 'distribute,' then 'a group formed by division,' giving modern meanings like class, team, or shift.
