花费英语怎么说

花费的英文是 "cost"。
这个词来源于拉丁文 "constare"，意思是 "站立，坚持"。在中世纪，这个词被用来指代物品的价格，就像我们现在说的 "价钱" 一样。
例句：
The cost of this book is ten dollars.
The cost of living in this city is very high.
I can't afford the cost of a new car.
The cost of the project was much higher than we had anticipated.
The cost of the trip includes airfare, hotel, and meals.
