蜜月
mì yuè · HSK 7
honeymoon
🍯🌙 蜜 (honey) + 月 (moon) = honeymoon, a calque of the English word
蜜 means honey and 月 means moon, so 蜜月 is a literal character-by-character borrowing of honeymoon. Same pronunciation logic helps: mì (honey) then yuè (moon).
蜜 — insect 虫 + 宓 (mì, phonetic)
蜜 is a semantic-phonetic compound. The 虫 component signals an insect (here, bees), while 宓 supplies the sound 'mì'. The character originally referred to honey produced by bees, and by extension came to mean sweetness.
月 — pictograph of crescent moon
月 is a pictograph of a crescent moon, chosen over a full circle to distinguish it from 日 (sun). The inner strokes originally depicted the moon's shadow or markings. As a radical it often relates to the moon, time, or (via a lookalike form of 肉 'flesh') body parts.
