What does "ค่าใช้จ่าย" mean in English?

The phrase "ค่าใช้จ่าย" in Thai translates directly to "cost" in English. This term is commonly used to refer to expenses or financial outlays associated with goods or services. Understanding this term is essential as it relates to discussions around budgeting, financial planning, and various contexts where costs are considered.

The other terms do not align with the meaning of "ค่าใช้จ่าย." For instance, "transportation" refers specifically to the means or process of moving people or goods from one place to another, which does not encompass the broader concept of cost. "Exam" refers to a formal assessment or evaluation of a person’s knowledge or skills and is entirely unrelated in meaning. Lastly, "library" denotes a place where books and other resources are kept for public use, which also does not connect to the concept of cost or expenses.
