So you're wondering whether to use 'would' or 'could' but need clarification on the difference between the two? This article will help.
In short, 'could' expresses possibility, and 'would' expresses intent. That is the short version, though, as it is more complicated than that. Read on to learn more.
'Could' or 'would' are both auxiliary verbs which means they assist another verb in the sentence. They are used to talk about situations that are currently imaginary. That isn't to say they won't come true, but for the moment, they are hypothetical.
'Could' feels more hypothetical, like a suggestion, while 'would' feels more certain, like an intention.
Or, quite simply, they can both be used to talk about an event in the past since they are, in fact, past tenses of root verbs.
- 'Could' is the past tense of 'can'
- 'Would' is the past tense of 'will.'
So let's take a more in-depth look at what the differences between each are.
There are many different ways you can use the word 'could.' The first is as the past tense of the verb 'can' to talk about things you used to be allowed or able to do. For example:
When I was a teenager, I could cycle to school if I wanted to.
The second use of the word 'could' is a polite way to ask for something.
Could you pass me the salt, please?
You can also use 'could' to form the subjunctive mood, which is used to express a wish or hypothetical situation. For example:
If I had lots of money, I could buy a house.
Many deaths could be prevented.
And finally, you can use 'could' to make a suggestion.
You could always hire someone to help with the extra workload.
Just like 'could,' there are also many different ways to use the word 'would.' The first is in the past tense form of the verb "will." That means we can talk about things we used to do in the past. For example:
When Paul was a teenager, he would cycle to school.
The difference between this example and the earlier one with 'could' is that this sentence is more definitive. Paul actually cycled to school in this last sentence. In the previous one, he said that he had the option to do that if he wanted to, but we don't know if he did.
'Would' can also be used as a polite way to ask for something, just like 'could.' The two words are interchangeable in this sense.
Would you pass me the salt, please?
You can also use 'would' to talk about hypothetical situations, but instead of talking about something that is merely a possibility, 'would' tells the listener what the reality would be.
If I had lots of money, I would buy a house.
Many deaths would be prevented.
These two examples are the same as I used earlier with 'could' because I wanted to show you that 'would' is much more definitive. If you're saying that with a smoking ban, many deaths "could" be prevented, you're saying that's an option. If you say that many deaths "would" be prevented, you're saying it is a certainty.
'Would' can also be used to talk about what someone was willing or unwilling to do. For example:
I asked him what had happened, but he wouldn't tell me.
And lastly, you can use 'would' "to refer to an intention from the point of view of the past." For example:
You said you would never get a dog.
Top tip! You can shorten "I would" to the contraction "I'd." That works with all the pronouns.

Knowing whether to use 'would' or 'could' can be pretty tricky, as it's only a fairly subtle difference. I think it often helps to remember the root form of the verbs "will" and "can." Remember: 'would' is an intention, and 'could' is a possibility.
