Difference Between Can and Could

Can, like could and would, is used to ask a polite question, but can is only used to ask permission to do or say something ("Can I borrow your car?" "Can I get you something to drink?"). Could is the past tense of can, but it also has uses apart from that--and that is where the confusion lies.

Which is correct could you or can you?

All are grammatically correct. Both are fine grammatically, but it appears that you are aiming for a relatively formal setting in which case "Could" is slightly more formal-sounding. Neither would be incorrect, however.

Can and could sentences examples?

We use could to show that something is possible, but not certain:

• They could come by car. (= Maybe they will come by car.) ...
• It can be very cold here in winter. ...
• That can't be true. ...
• It's ten o'clock. ...
• It could be very cold there in winter. ...
• They know the way here. ...
• She can speak several languages. ...
• I can see you.

What is the difference between able and could?

When talking/writing about past ability you can use 'could' or 'was/were able to' in order to discuss an ability that existed for a long time, but now no longer exists. Examples: ... But you should only use 'was/were able to' with action verbs to talk about an ability related to a single event or incident in the past.

Where we can use could and would?

Could, would, and should are all used to talk about possible events or situations, but each one tells us something different. Could is used to say that an action or event is possible. Would is used to talk about a possible or imagined situation, and is often used when that possible situation is not going to happen.

Where is could used?

"Could" is a modal verb used to express possibility or past ability as well as to make suggestions and requests. "Could" is also commonly used in conditional sentences as the conditional form of "can." Examples: Extreme rain could cause the river to flood the city.

Is could you please rude?

They're not impolite -- they're just less polite than the versions with please.

Can have examples?

Here are some more examples:

I couldn't have said it better myself. We could have left the party earlier. The girl was crying because she couldn't find her parents. You could have stopped by the grocery store.

What do can and could express?

We all know how important it is to be able to express in English the ability or the possibility to do something, but English grammar can be tricky. So can and could are modal auxiliary verbs that express an ability, permission, request, offer or opportunity.

Can able is correct?

This may be common in Indian English. However, it's certainly not accepted as Standard English because, as you say, can and be able to have the same meaning. Because able to isn't a verb but part of an adjectival phrase, it requires a verb; but as it's adjectival that verb is be, not can.

Was able in a sentence?

Use it when you want to say that someone or something started (and completed) an action in the past: I was able to fix the faucet and now it's fine. (In this sentence, the faucet was fixed sometime before the time being spoken of).
