舗装
ほそう · hosou · JLPT N1 · noun
road surface
🛣️ 舗 (pave) + 装 (dress/equip): paving = dressing up the road with a hard surface
舗 means to pave and 装 means to equip or dress. Together they say the road gets dressed in a hard surface, and 舗装 names that surface too.
装 — clothes 衣 + strong 壮 (phonetic)
装 is a semantic-phonetic compound. The bottom 衣 ('clothes') gives the meaning, since the original sense was packing or dressing—putting clothes or goods into a bundle. The top 壮 supplies the sound. Meanings extended from 'to dress/attire' to 'to load, install, pretend'.
