🔹Main Difference – Could vs Would
Could and would are two modal verbs that often confuse English learners. Although both words can sometimes have similar meanings, these two verbs have specific functions. Could is the past tense of can and would is the past tense of will. Could indicates an ability whereas would indicates a possibility. This is the main difference between could and would.

🖇 Could – Meaning and Usage
Could is the past tense of can. Could can be used to express a possibility, ability, requests and permission. The use of could makes a sentence more polite and formal. You can notice these features by looking at the examples below.

We could have helped her.

You could have told me the truth.

The old man couldn’t hear anything before the operation.

When we were young, we could run so fast.

Could I ask some questions?

Could you please close the door?

Could I get you something to drink?

When could is used to indicate a possibility, could implies a weaker possibility (than can). Unlike can, could is only used to ask for permission; it cannot be used to grant permission. Most importantly, could is more formal than can.

🖇 Would – Meaning and Usage
Would is the past tense of will. Would can be used when talking about future in the past as well as in reported speech. It is also used in the formation of conditional clauses. Here, would indicates an imaginary or an impossible situation. Since would is the past form of will, it is also used to describe what people wanted to do or were willing to do.

He promised me that he would meet her next day.

She would let him eat in the dining hall when nobody was at home.

If you had helped me, I would have been successful.

If I were you, I would kill him.

If we had money, we would go abroad.

Would can also be used to express a wish, preference, offer, or request more politely since it is considered to be more polite and formal than will.

Would you like to have a cup of coffee – Offer

I would like to speak to you alone.– Request

I would rather kill myself than surrender. – Preference

I would like to travel the world one day. – Wish
