箱
はこ · hako · JLPT N5 · noun
box
📦 箱 = bamboo 竹 + 相 (sound part): originally a bamboo-woven box
The top radical 竹 means bamboo, the material old boxes and trunks were woven from. The bottom 相 only lends its sound. For the reading: hako sounds like HAckle + COat, or just think 'HA, a KOntainer!' — ha-ko holds things.
箱 — bamboo radical 竹 + 相 (xiāng) phonetic
A semantic-phonetic compound. The bamboo radical 竹 on top signals the original meaning: a box or chest woven from bamboo or made of wood. The component 相 below supplies the sound 'xiāng'. Over time the meaning broadened from bamboo containers to boxes and cases of any material.
