頂点
ちょうてん · chouten · JLPT N2 · noun
top
⛰️ 頂 (top) + 点 (point) = the highest point, the peak of something
頂 is the kanji for top or summit (いただき), and 点 means point. Together they name the single highest point of a mountain or any other thing.
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.
