Have To vs. Need To vs. Must – What’s the difference in English?
- I need to go to the store.
- I have to go to the store.
- I must go to the store.
- I need to go now.
- I have to go now.
- I must go now.
Do these sentences mean the same thing? Can we always use them in the same way?
Let’s find out in today’s Confident English lesson.
Need to vs. have to vs. must can be used as synonyms. Sometimes. That’s the good news.
Generally, they all mean that you’re talking about a responsibility, an obligation, or something that is important to do. This is where they are similar. In positive sentences.
But there are some small differences in connotation and how we use them. (Connotation is the feeling or idea a word gives in addition to its meaning.)
And then, in negative sentences (for example, don’t have to and mustn’t), the meanings are not at all similar.
This means you must be careful about which verb you use. Let’s take a closer look at how English speakers use these verbs in everyday conversation. I want you to learn how to use them in the same way.
What do these mean in real daily English? How are they similar or different?
Lesson by Annemarie
Practice Have to, Need to, and Must in English
Now that you’ve watched the lesson, let’s get some practice. You can share with me in the comments below. And when you do, it means you’ll get feedback from me, so don’t miss that opportunity.
- To start, tell me something that you need to do this week. This means it’s something that is important to you.
- Now share with me a work or study obligation you have soon. Maybe it’s this week. Maybe next weekend. But it is a necessity for work or school.
- Can you give me an example of something that you really want or desire using the correct verbs from our lesson?
- And finally, give me an example of something that is your choice. Maybe you have the option to do something this weekend. What is it?
With these examples, be sure to follow the general rules from the lesson about whether you should use need to, have to, or must in the positive and negative forms.
Have a great week!
Annemarie

Hi Annemarie, This is the first time I have watched your video. I was brushing up on my modal verbs and I chanced upon your video . I am a teacher myself.

I would like to emulate some of the above mentioned aspects in my training too. Thank you for the efforts and time invested in making the video and responding to the participants. Look forward to watching more… Read more »

Hi Sohyun,
Thank you for sharing your answers with these easily confused words. Nice work!
One question, can you clarify what you mean by, “…but you wouldn’t have to go there if you had your plan.”
This is an answer of your question; I don’t want to give pressure to the listener. The situation is I had a dinner yesterday at the restaurant. It was so nice that I recommend the restaurant but meaning no obligation. In Korea, we don’t have the intonation and some in trospective people think the recommendation is as a pressure or necesssary, so when ever I ment suggestion or recommendation I say you shouldn’t go there , it’s up to you or if you had your plan you wouldn’t need to go there. Sorry for replying it lately Thank you for… Read more »
Hello Sohyun,

I mustn’t attend a meeting this week.
Hi Lilia,
I’m glad to know this lesson was helpful. And thank you for sharing your examples!
Can I ask, why is it important to you to go swimming on the weekends?
And, with “I mustn’t attend a meeting this week.” –> This means it’s prohibited (not allowed, not acceptable) for you to attend a meeting. Is that what you wanted to say? If not, what might you change?
Thank you for your interested. I like to go to swimming pool because it is healthy and helping me to relax.
I didn’t have a meeting this week. I will have the meeting for next week.
I need to investigate in a complex data system to find an error which currently occures.

For calming down on weekend I haven’t to take a look in my emails.
For feeling more confident in English I have to practise daily.
I like your example with mustn’t and it’s very true. For the fourth example, let’s change the word order just a bit. If you start the sentence with, I don’t have to look at my emails on the weekend which… –> how would you finish it?
I don’t have to look at my emails on the weekend which helps me to calm down.
Thank you for your respond and interest.
