How to Explain Pay vs. Spend vs. Cost
Similar to "say" and "tell," there are small but important differences between "pay," "spend" and "cost" that can be difficult for students to catch. These are essential vocabulary words that all English learners should master, so let's look at some ways we can explain each of them and their unique uses to our students.
Pay
Let's begin with "pay," which is mostly used as a verb meaning “to give money in return for work, goods, services, etc.” The focus is on an action someone is performing.
Someone pays (for something).
Neither “spend” nor “cost” can be used in these examples.
Spend
Next, "spend" as a verb means “to use up” or “to give money for goods or services.” This is almost the same as the definition for “pay!” Sometimes you can use either word without changing a sentence’s meaning, but you’ll need to change the preposition.
But in other situations, you cannot do this. For example, you cannot say “spend the cashier” or “spend a late fee.”
So what makes "spend" unique? It is used to focus on the payment itself. In other words, a sentence with “spend” is about the money being exchanged.
Someone spends (an amount) on something.
Cost
Finally, the verb “cost” means “to require payment before something can be received or done.” So the focus of a "cost" sentence is on the item or service that must be paid for, not the person performing the action or the amount being paid.
An item or service costs something.
Again, the other two verbs would not work in these sentences.
So, let's review:
Noun Forms
We've covered some of the main uses in the verb forms, but each of these words can also be used as nouns.
"Pay" as a noun refers to money someone receives as a reward for work.
The noun form of "spend" isn't common in daily conversation. It means "the amount of money spent for a particular purpose over a particular length of time." It's mostly used in business situations.
As a noun, "cost" means "the amount of money you have to pay in order to buy or do something."
Other Uses
These words are not only used to talk about money, so let's look at some other ways to use them.
"Pay" means "give" when used together with specific words.
“Spend” can refer to time as well as money.
“Cost” can be used to say that something has been lost or that something bad is now necessary.
Conclusion
The differences between these three verbs can be tricky for students at first, but explaining things in this way will hopefully make it easier for them to understand the unique way each is used. Once they know the focus of their sentence, choosing the correct verb will be simpler, and they will be better prepared to talk about their shopping experiences.
