A millionaire is someone with at least a million pounds or dollars — very rich. People also stretch it: “He spends like a millionaire” can mean only that someone throws money around, not that they have counted a million in the bank.

A millionaire百萬富翁 is是 someone with at least a million pounds or dollars至少擁有一百萬英鎊或美元的人——very rich非常有錢。People人們 also stretch it也會延伸這個字的用法："He spends like a millionaire"「他花錢像個百萬富翁」 can mean only可能只是說 that someone throws money around某人亂花錢，not that they have counted a million in the bank不代表他銀行裡真的存了一百萬。

The word is common and a little admiring; it is not slang, and it is not stiff.

The word這個字 is common很常見，and a little admiring帶點欣賞的味道；it它 is not slang不是俚語，and it is not stiff也不生硬。

Though actually, a million does not buy what it bought a hundred years ago, so the fairy-tale shine has faded a little — but the word still means “at least a million.” English borrowed the whole word from French millionnaire; it looks like million plus a tail, and that surface reading is fair.

Though actually不過事實上，a million一百萬 does not buy what it bought a hundred years ago現在買不到一百年前能買的東西，so所以 the fairy-tale shine那種童話般的光環 has faded a little已經淡了一些——but但 the word這個字 still means仍然的意思是 "at least a million."「至少一百萬」。English英語 borrowed the whole word整個字是借來的 from French millionnaire從法語millionnaire；it它 looks like看起來就是 million plus a tailmillion加上一個字尾，and而 that surface reading is fair這樣的表面解讀是合理的。
