If I could, I would. But how would that happen? Let’s explore the possibilities. Would it be a good idea? Would it be possible to have a child or an animal? Could you live happily ever after? These are just some examples of situations where would be useful. It can also be used as a request, an order, or an instruction. In some contexts, would means “to do” or “to do something.”
Could is a form of the verb could in the past subjunctive. It means that something can be done or accomplished, but this use is a bit more complex than that of’must.’ However, it can still be used to express an intention or indicate a possibility. When referring to permission, could can be replaced by can or might. Could is often used in conditional sentences, and the former is the default form.
Could is often used in a reporting structure: “She said she spoke Arabic.” Similarly, be able to is used after verbs or modals. Both can and could are used with sense verbs and are often referred to as a possibility. As a result, could is the preferred form when referring to a possible ability, or the possibility of doing something. And could is an excellent option for describing a possibility.
Although could and would seem to be interchangeable, good writers know how to properly use them. There are a number of situations where a person would be able to do something. Learn to differentiate between these two verbs so you can avoid a grammatical mess. You’ll be glad you learned the difference between them. The two verbs are similar but have different meanings. They express past ability, possibility, and certainty. Using could in writing requires a bit more practice.
