零 — rain 雨 + order 令 (phonetic)
A semantic-phonetic compound: 雨 (rain) gives the meaning and 令 supplies the sound. It originally meant scattered drops of falling rain, then extended to 'fragmentary, leftover bits,' and in modern Chinese came to mean 'zero.'
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.
