Let's talk about the difference between cannot, can not and can't. Let's start with cannot as one word. So really pay attention that this is one word and spelling, we have two ends, but it's in one word. Now, cannot is the negative form of the verb can. That's it. Simple as that. So let's take a positive sentence with can. I could say, I can pick you up at the airport. I can pick you up at the airport. That's a positive sentence, but if I want to make this sentence negative, all I need to do is change can with cannot. Remember, one word, two ends. So that would be I cannot pick you up at the airport. So to make a positive can sentence negative, simply use one word cannot and replace that with can. It's as simple as that. Now let's talk about can't. Notice the spelling. There's one end and it's a contraction, right? Every time you see the apostrophe, you know it's a contraction. So can't is just the contracted form of cannot. You can think of it as the short form. Now you use it in the exact same way. So we take our positive sentence, I can pick you up at the airport. And then to make it negative, we just change it with can't. Can't. I can't pick you up at the airport. Can't is more common than using cannot, the longer form. Now let's talk about cannot as two words. First of all, know that this is not the negative form of the verb can. Okay, it's not the negative form. If you use it as the negative form in spoken English, you won't hear a difference. But in written English, if you use can not as two words, it's a spelling mistake. As simple as that, it's a spelling mistake. Okay, because the correct spelling of the negative form of can is cannot one word. But can not as two words still exist, but it's not very commonly used. We can use it, for example, when you have not in one part of a sentence, and then can is just your verb of that sentence, but can and not when they're two words aren't together. Okay, their relationship isn't together. So for example, you're probably familiar with the expression, not only, but. That's a very common expression in English, not only X, but also why not only, but. So notice in this expression, I have the word not not only. Now, theoretically, my verb in this sentence could be can. And if that's the case, you might see can and not side by side, but they're not together. It's not making can negative, not relates to not only, but or another expression that uses not. So for example, I could say, I can not only pick you up at the airport, I can also help you unpack. Okay, just to give an example. So notice, I can now not only pick you up at the airport. So can is just the verb in the sentence. It's not connected with not only, but I can not only pick you up at the airport, I can also help you unpack. So that's just theoretically, you could see can and not side by side as two separate words. But honestly, that's not very common. And I don't think you're going to see that when you see can and not side by side as two words. Most likely it's just a spelling mistake and they wanted to make can negative, which is one word cannot. So to summarize, cannot as one word is the negative form of can. Can is a contraction of cannot is the most commonly used can not as two words is possible, but is not the negative form of the verb can. So now you know how to use these. And now of course, it's your turn to practice. I want you to leave three examples, one with cannot the negative form, one with can the contraction, and then why not try I can not only, but that would be a pretty advanced structure to practice.
