泡泡本身：看得見的，和會破的
這一支貼著字面：bubble ＋ -y ＝ 有泡泡的。分成兩面——真的看得到泡泡，以及拿泡泡「外大內空」的性質來作判斷。
adjective · B1
Full of small bubbles, or making a lot of them. Used about drinks, water, and mixtures such as soap or beaten egg white.
冒泡的；有氣泡的
核心畫面
One way to hold this word: a glass just poured, with small bubbles climbing up the side and never quite stopping. Two things about that glass matter, and English uses both. The rising never stops — so a person can be bubbly, with that keeps coming up. And a bubble is big on the outside and empty inside, ready to go at a touch — so a market can be bubbly, priced high on nothing much. The drink named bubbly sits right in the middle: it is called after the very thing you are looking at.

「bubbly」可以想成一杯剛倒好的飲料：小泡泡沿著杯壁一顆顆往上衝，而且停不下來。這個畫面有兩個重點，英文兩個都拿去用了。一是「一直往上冒」——所以人可以 bubbly，那股開朗像泡泡一樣不斷湧出來。二是「外面大、裡面空，一碰就破」——所以市場可以 bubbly，價格撐在幾乎空的東西上面。至於被叫做 bubbly 的那杯酒，就站在畫面正中央：名字直接取自你眼前看到的氣泡。From the word’s history
The source gives the make-up of the word plainly: bubble plus the adjective ending -y. So the literal meaning is 'having bubbles', and every other use in this entry can be read as that picture put to work somewhere else.
資料直接寫出了這個字的組成：bubble 加上形容詞字尾 -y。所以它字面就是「有泡泡的」。這個條目裡其他的用法，都可以想成是把同一個畫面搬到別的地方去用。
