⛰️ 难点 = 难 difficult + 点 point = the difficult point, a sticking point
难 means difficult and 点 means point or spot, so 难点 is literally the difficult spot — the one tricky point in a task or lesson where people get stuck.
难 — 又 (right hand) + 隹 (short-tailed bird)
Originally written with 堇 (clay) plus 隹 (bird), 難 depicted a rare bird and was borrowed to mean 'difficult.' The modern simplified form replaces the left side with 又 (hand). The phonetic role of the original left component gave the reading nán.
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.
