採点

🏆 採 (pick, choose) + 点 (point, score): picking points to mark a score = marking or grading
採点 literally means 'picking points': a teacher picks out the correct points and assigns marks. Think of the 点 as the red dot or check mark a teacher adds when grading.
点 — fire radical 灬 + 占 (zhān, phonetic)
Originally written 點, a semantic-phonetic compound: 黑 (black) gave the meaning 'small black mark or dot' while 占 supplied the sound. It first referred to ink spots, then extended to 'point, drop, a little,' and verbs like 'to mark' or 'to light (a fire),' reflected in the simplified form's 灬 (fire) component.
