花瓶
かびん · kabin · JLPT N5 · noun
vase
🏺💐 花瓶 = flower (花 ka) + bottle/jar (瓶 bin): a flower-bottle
花 is flower, read ka here (as in 花粉 kafun, pollen). 瓶 is bottle, read bin (as in ビール瓶, beer bottle). A vase is literally a bottle for flowers. Sound hook: kabin is one letter off cabin, and a cabin table wants a vase.
花 — grass radical 艹 + 化 (change/phonetic)
花 is a semantic-phonetic compound. The top 艹 (grass) signals the plant meaning, while 化 ('change, transform') gives the sound and hints at how buds change into blossoms. It originally meant 'flower' or 'blossom' and later extended to 'flowery, patterned, to spend.'
瓶 — 併 (bing, phonetic) + 瓦 (tile/pottery)
瓶 is a phono-semantic compound. The right side 瓦 means tile or earthenware, signaling that the object is made of clay or pottery. The left side 并/併 supplies the sound 'ping'. Originally it referred to a pottery jar or jug, later generalized to any bottle or vase.
