A groundswell is when a feeling grows quickly among a lot of people — support, anger, hope — as if it rose up from underneath. You often cannot point to one leader who started it; it feels as if the crowd itself began to move.

A groundswell Groundswell is指的是 when a feeling grows quickly among a lot of people一種感覺在很多人之間迅速蔓延──support, anger, hope支持、憤怒、希望──as if it rose up from underneath就好像是從底下湧上來的。You often cannot point to one leader who started it你常常沒辦法指出是哪一個帶頭的人開始的；it feels as if感覺就像 the crowd itself began to move群眾自己開始動起來一樣。

The picture comes from the sea: a swell is a long, slow wave that started far away. Even when the water near you looks quiet, that wave is already on its way.

The picture comes from the sea這個畫面來自大海：a swell swell is a long, slow wave that started far away指的是一種從遠方開始、又長又緩慢的浪。Even when the water near you looks quiet就算你附近的海水看起來很平靜，that wave is already on its way那道浪其實已經在路上了。

Writers borrowed the word for public feeling. It is a bit formal. You meet it in news and speeches more than in everyday chat.

Writers作家 borrowed the word借用這個字 for public feeling來指公眾的情緒。It它 is a bit formal有點正式。You meet it你會遇到它 in news and speeches在新聞和演講裡 more than in everyday chat比在日常聊天裡更常見。

Though actually, it is not the ground swelling up, like a bump in the earth. The “ground” here is from the old sea picture, not from soil.

Though actually不過其實，it is not the ground swelling up這不是指地面鼓起來，like a bump in the earth像地上的一個突起那樣。The "ground" here這裡的「ground」 is from the old sea picture是來自那個古老的海洋畫面，not from soil不是來自土壤。
