点燃
diǎnrán · HSK 5
to ignite; to set on fire
🔥 点 = dot/ignite + 燃 = burn → strike a dot to make it burn
点 means a dot or to light/spark; 燃 means to burn or combust (fire radical 火 on the left). Together 点燃 is to spark something into burning — to kindle or ignite a fire, fuel, or by extension passion.
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.
