Can and could: ability, permission and requests
Use can and could to describe skills, ask permission, request help and suggest a plan. Practice the forms and choose meanings from everyday situations.
Use need and want with things and actions, ask questions, explain a purpose, and make a simple request.

Read the examples, then check each idea as you go.
Use need when you say that something is necessary. Use want when you say what you would like. Both words can name a thing or introduce an action. The choice tells the listener how you see the situation.
Choose need to say that something is necessary for you or for a task. The need can be small and practical, such as a pen for a form. It does not have to be an emergency.
Choose want to say what you would like to have or do. The same thing can be a need in one situation and a want in another. These words express the speaker's meaning; they do not put every object into a fixed group.
I need a pen to sign this form.
I want a green pen because I like the color.
Put the thing directly after need or want. For one countable thing, use a complete phrase such as a bag, this key or my phone. Do not add to before the name of the thing.
Water and help do not usually take a or an. You can use some with these words when you mean an amount. Plural things can follow need or want with a number or another suitable word.
We need two chairs.
I want some water.
Use need to or want to when the next word names an action. Keep the action in its basic form: to leave, to eat or to buy. The person before need or want does that action in this pattern.
Keep to when you add more words after the action. Need to buy a ticket describes a necessary action; want to buy a ticket describes a wish. The word ticket does not remove the to before buy.
We need to leave at eight.
I want to cook dinner tonight.
In a present simple statement, use needs and wants after he, she, it or one person's name. Use need and want after I, you, we and they. Both words are verbs here, so you do not put am or is before them.
Only the first verb changes in the action pattern. After needs to or wants to, the next verb stays in its basic form. For these simple statements about needs and wishes, use the present simple.
Sam needs a new notebook.
She wants to sit near the door.
Start a simple yes/no question with do for I, you, we or they. Use does for he, she, it or one person's name. After do or does, use need or want without -s.
You can ask about a thing or an action. Keep to when the question includes an action. A short answer can use do or does instead of repeating the whole question.
Do you want some juice? Yes, I do.
Does Rosa need to leave? Yes, she does.
Don't need means something is not necessary. It does not mean that you are not allowed to have it or do it. Don't want means that you would not like it.
Use doesn't with he, she, it or one name. Keep need or want without -s after doesn't. In the action pattern, keep to before the next verb.
You don't need to bring a chair. We have enough.
I don't want to sit outside. It's cold.
Use for + a person or thing to say who will use something or what it is for. A bag for the trip tells us why the bag is needed. A drink for my friend tells us who will receive it.
The purpose does not change need into want. Choose the first verb from your meaning, then add for to make the request clearer. Use to + verb instead when you name an action.
We need a table for the meeting.
I want a small gift for my sister.
Want is useful when you tell someone your choice. In a shop or cafe, I'd like is a useful polite way to ask for that choice. I'd like means I would like.
You can put a thing after I'd like or use I'd like to + action. Adding please helps mark the request. You can still state a real need directly, especially when explaining why you are asking.
I'd like a small tea, please.
I need a ticket for today. I'd like to leave before lunch.
Try the questions in order. Use a hint when you need one, then read the explanation after checking.
Plan a short trip. Write four sentences: one thing you need, one action you need to do, something you want, and a polite request with I'd like. Add a reason or purpose to one sentence.
Write in English, then compare your writing with the checklist. This activity uses self-review, so it does not give a score.
I need a bag for the trip. I need to buy a train ticket. I want to sit with my friend. I'd like two seats together, please.
