A2 phrase #1,000 most common 13 min read

of course

Top 1,000

At the A1 level, 'of course' is a very helpful phrase for saying 'yes' in a friendly way. It is a 'chunk' of language, which means you can learn it as one piece without worrying about the grammar of the individual words. Use it when someone asks you for a simple favor or asks if you like something. For example, if someone asks, 'Do you like coffee?' you can say, 'Of course!' to show you really like it. It makes your English sound more natural than just saying 'yes.' It is a polite and easy way to agree with people. You will hear it often in simple conversations and in English class. Remember, it is two words: 'of' and 'course.' You can also use 'of course not' to say 'no' very strongly. For example, 'Are you tired?' 'Of course not!' This shows you have a lot of energy. Learning this phrase early will help you feel more confident when talking to others. It is one of the first 'idiomatic' expressions most students learn because it is so common and useful in daily life.

At the A2 level, you can start using 'of course' to show that something is expected or obvious. This is slightly more advanced than just using it to say 'yes.' For example, you might say, 'Of course, it is cold in winter.' This shows you understand how the world works. You can also use it to give permission more politely. If a classmate asks, 'Can I borrow your pen?' saying 'Of course' is much nicer than just saying 'Yes.' It shows you are happy to help. You should also notice that 'of course' can go at the beginning or the end of a sentence. 'Of course I will help you' and 'I will help you, of course' are both correct. At this level, you should also be careful not to use it in a way that sounds rude. If someone asks a question because they really don't know the answer, saying 'of course' might make them feel bad. Use it mostly for agreement and for things that everyone knows are true. It's a great way to add more variety to your speaking and to sound more like a native speaker.

By the B1 level, you should be comfortable using 'of course' in both spoken and written English. You can use it as a 'discourse marker' to help organize your thoughts. For example, you can use it to acknowledge a point before you say something else: 'Of course, the price is important, but the quality is more important.' This shows you are thinking about different sides of an argument. You should also start using commas correctly when 'of course' is in the middle of a sentence. For example: 'The train, of course, was late.' This makes your writing look more professional. At B1, you can also use 'of course' to express sarcasm or irony, though you should be careful with this. If something bad happens that you expected, you might say, 'Of course it's raining!' with a specific tone of voice. This shows you are frustrated but not surprised. You are also learning other words like 'certainly' and 'naturally,' so you can start choosing the best word for the situation. 'Of course' is great for general use, but 'certainly' might be better for a formal letter or a job interview.

At the B2 level, you can use 'of course' to handle more complex social and professional interactions. You understand the nuance of the phrase and can use it to build rapport or to subtly influence a conversation. For instance, you might use it to confirm a logical deduction: 'If the sales are up, then of course the profits will increase.' This shows you can follow a logical path and express it clearly. You are also aware of the 'concessive' use of 'of course,' where you admit a fact that might go against your main point, only to then reinforce your main point. This is a key skill for persuasive writing and debating. You also know when *not* to use 'of course' to avoid sounding patronizing. You might choose 'naturally' or 'as one might expect' in more formal academic writing to maintain a neutral tone. Your use of 'of course' is now integrated into your overall fluency, allowing you to sound more natural and less like you are translating from your native language. You can also recognize when others use it sarcastically or to project authority in media and politics.

At the C1 level, your use of 'of course' is sophisticated and precise. You use it to manage the flow of information in long, complex sentences and to signal your stance on various topics. You are a master of its placement, using it parenthetically to add a layer of commentary or at the beginning of a paragraph to link it to a previous idea. You understand the historical and cultural weight of the phrase and can use it to navigate high-level professional environments. For example, in a legal or business negotiation, you might use 'of course' to establish common ground before moving into more contentious areas: 'Of course, we both want this partnership to succeed.' This uses the phrase as a strategic tool for consensus-building. You are also sensitive to the subtle differences between 'of course,' 'it goes without saying,' and 'needless to say,' choosing the one that perfectly fits the register and tone of your communication. Your ability to use 'of course' sarcastically is also highly developed, allowing you to use it for humor or social critique in a way that is perfectly understood by your audience.

At the C2 level, 'of course' is a tool you use with total native-like intuition. You can use it to create complex rhetorical effects, such as irony, understatement, or hyperbole. You understand how its meaning can shift based on the tiniest change in intonation or context. You can use it in highly formal academic papers, where it serves to acknowledge established scholarship before you present your own original findings. You are also aware of how 'of course' functions in different dialects of English and can adjust your usage accordingly. In creative writing, you use the phrase to reveal deep insights into a character's worldview or social status. You might use it to show a character's arrogance, their sense of entitlement, or their deep-seated assumptions about their environment. At this level, you don't just 'use' the phrase; you play with it, using it to add texture and depth to your communication. You are fully aware of its potential for both connection and alienation and use it with the care and precision of a master communicator.

Practice it Examples Notes & Tips

of course in 30 Seconds

Used to express strong agreement or a very positive 'yes' to a request.
Indicates that a fact is obvious, expected, or naturally true.
Can be used at the beginning, middle, or end of a sentence.
Must be used carefully to avoid sounding rude or condescending.

The phrase 'of course' is one of the most versatile and frequently used expressions in the English language. At its core, it serves two primary functions: to express strong agreement or permission, and to indicate that something is obvious or expected. When you say 'of course' in response to a request, you are not just saying 'yes'; you are saying 'yes, and it should be obvious that I would agree.' This adds a layer of warmth and certainty to your communication. For example, if a friend asks, 'Can you help me move this table?' and you respond with 'Of course,' you are signaling that you are more than willing to help and that they shouldn't have even felt the need to ask because your friendship makes the answer certain.

Agreement: Used to give a very positive 'yes' to a question or request.
Obviousness: Used to state that a fact is naturally true or expected by everyone.

'Will you be at the wedding?' 'Of course! I wouldn't miss it for the world.'

However, the phrase carries a subtle social risk. Because it implies that something is obvious, using it to answer a factual question can sometimes come across as condescending or rude. If someone asks, 'Is the sun a star?' and you reply, 'Of course,' you might unintentionally make the questioner feel unintelligent for asking. In professional settings, it is often used to confirm understanding of a logical progression or a standard procedure. It bridges the gap between simple confirmation and shared knowledge. In literature and film, 'of course' is often used to reveal a character's confidence or their assumptions about the world around them.

'Of course, we must consider the budget before making a final decision.'

The phrase also appears frequently in the middle of sentences to provide a logical link. It functions similarly to 'naturally' or 'as expected.' When used this way, it often requires commas on both sides: 'The results, of course, were exactly what the scientists predicted.' This usage guides the reader or listener to accept the statement as a logical conclusion. It is a powerful tool for building persuasive arguments because it frames your points as being self-evidently true.

'Of course, there are exceptions to every rule.'

Permission: 'May I sit here?' 'Of course you may.'

'Of course, I'll have the report ready by Monday morning.'

In summary, 'of course' is a linguistic multi-tool. It builds rapport, confirms facts, grants permission, and structures logical flow. Understanding the nuance between its 'polite agreement' and 'obvious fact' meanings is key to mastering its use in daily English conversation. Whether you are reassuring a friend or presenting a business case, 'of course' provides the emphasis and clarity needed to make your point effectively.

Using 'of course' correctly involves understanding its placement and the punctuation that accompanies it. It can appear at the beginning, middle, or end of a sentence, and each position carries a slightly different weight. When placed at the beginning of a sentence, it often acts as a transition or a strong opening to an agreement. For example, 'Of course, we will need to verify the data.' Here, it sets the tone for the entire statement, indicating that the need for verification is a given.

Sentence Starter: 'Of course, I will help you with your homework.'
Parenthetical: 'The weather, of course, was terrible on the day of the picnic.'

'You can borrow my car, of course.'

When used in the middle of a sentence, 'of course' is usually set off by commas. This is because it functions as a parenthetical expression—a comment that is added to the sentence but is not grammatically essential to its structure. 'The manager, of course, was the last to know about the changes.' This usage emphasizes that the manager's lack of knowledge was expected or typical of the situation. It adds a layer of commentary to the factual information being presented.

At the end of a sentence, 'of course' often acts as an afterthought or a final confirmation. 'I'll be there, of course.' This placement is very common in spoken English and serves to reassure the listener. It rounds off the sentence with a note of certainty. It is also used in the negative form 'of course not' to provide a strong 'no.' 'Did you forget my birthday?' 'Of course not!' In this context, the phrase is essential for showing that the very idea of forgetting is impossible.

'Of course not, I would never do that to you.'

Negative Response: 'Are you angry?' 'Of course not!'

'There are, of course, many ways to solve this problem.'

One advanced way to use 'of course' is in 'concessive' structures. This is where you acknowledge a fact before presenting a contrasting point. 'Of course, the initial cost is high, but the long-term savings are significant.' Here, 'of course' helps you build a balanced argument by showing that you have considered the obvious drawbacks before reaching your conclusion. This makes your final point more persuasive and credible.

'Of course, we want to win, but playing fairly is more important.'

In summary, the placement of 'of course' dictates its rhythm and emphasis. Whether you are using it to start a sentence with confidence, adding it as a logical middle-ground comment, or ending with a reassuring confirmation, the phrase is a vital component of natural-sounding English. Pay attention to how native speakers use it in different contexts to get a feel for the subtle shifts in meaning that come with its position.

In the real world, 'of course' is ubiquitous. You will hear it in coffee shops, boardrooms, movie scripts, and casual phone calls. In customer service, it is a standard phrase used to show willingness and professionalism. When a customer asks, 'Can I get a refill on my coffee?' a waiter will almost always respond with 'Of course' or 'Certainly.' In this context, 'of course' is a polite way of saying that the request is standard and will be fulfilled immediately. It creates a positive and helpful atmosphere.

'Can I see the menu?' 'Of course, here it is.'

In movies and television, 'of course' is often used to highlight a character's personality. A confident hero might use it to show they are in control: 'Of course I have a plan.' Conversely, a sarcastic character might use it to mock someone: 'Oh, of course, because you're always right!' The tone of voice and facial expression are crucial here. In a sarcastic context, the phrase is drawn out and the emphasis is placed heavily on the word 'course.' This demonstrates how the same two words can convey completely opposite meanings based on delivery.

Customer Service: Used to make customers feel that their requests are normal and welcome.
Sarcasm: Used with a specific tone to mean the exact opposite of agreement.

'Of course, it starts raining just as we leave the house!'

In academic and professional lectures, 'of course' is used to guide the audience through complex ideas. A professor might say, 'Of course, we are assuming the environment is a vacuum for this calculation.' This tells the students that the assumption is a standard part of the process and shouldn't be questioned at this stage. It helps maintain the flow of the lecture by acknowledging potential questions before they are even asked. It creates a shared intellectual ground between the speaker and the audience.

In daily family life, 'of course' is a way to express love and support. 'Will you come to my school play?' 'Of course I will!' In this setting, the phrase carries an emotional weight, reinforcing the bond between family members. It says, 'You are important to me, so your events are important to me.' It is a simple phrase that does a lot of work in maintaining relationships. Whether it's a small favor or a major life event, 'of course' provides the necessary reassurance that someone is there for you.

'Of course I love you, why would you even ask?'

Finally, you'll hear 'of course' in news reporting and political speeches. Journalists use it to state facts that are widely known: 'The President, of course, has the power to veto the bill.' Politicians use it to frame their policies as common sense: 'Of course, we want to lower taxes for everyone.' In these high-stakes environments, the phrase is a rhetorical tool used to build consensus and project authority. It is a small phrase with a big impact on how information is perceived by the public.

One of the most common mistakes learners make with 'of course' is using it in situations where it might sound rude or dismissive. Because 'of course' implies that something is obvious, using it to answer a genuine question can make the other person feel like they asked a 'stupid' question. For example, if someone asks, 'Do I need a passport to travel to France?' and you reply, 'Of course,' it might sound like you are mocking their lack of knowledge. A better response would be 'Yes, you do,' or 'Yes, definitely.'

The 'Duh' Factor: Avoid using 'of course' for factual answers where the answer might not be obvious to everyone.
Overuse: Using it in every sentence can make your speech sound repetitive and overly insistent.

Mistake: 'Is 2+2 four?' 'Of course.' (Can sound rude)

Another mistake is confusing 'of course' with 'sure' or 'okay' in terms of formality. While 'of course' is generally polite, it is more formal than 'sure.' In a very casual setting with close friends, 'of course' might sound a bit too stiff. Conversely, in a very formal business meeting, 'sure' might sound too casual. Understanding the 'register' or level of formality of your environment is key. 'Of course' is a safe middle ground, but it's important to be aware of the alternatives.

Punctuation mistakes are also frequent in writing. Many people forget to use commas when 'of course' is used as a parenthetical expression in the middle of a sentence. Writing 'The results of course were good' is technically incorrect; it should be 'The results, of course, were good.' The commas help the reader understand that 'of course' is a side comment and not a core part of the subject or verb. This small detail can make a big difference in the professional quality of your writing.

Correct: 'The train, of course, was late again.'

A final common error is using 'of course' when you actually mean 'off course.' These are two very different expressions. 'Of course' (two words) means certainly or naturally. 'Off course' (two words, with 'off') means away from the intended path or direction. For example, 'The ship was blown off course by the storm.' Confusing these two can lead to significant misunderstandings, especially in written communication. Always double-check your spelling to ensure you are using the correct phrase for the context.

'We are off course and need to find the map!' (Wrong spelling for 'certainly')

In summary, while 'of course' is a helpful phrase, it requires careful handling. Be mindful of your tone to avoid sounding dismissive, use correct punctuation in writing, and don't confuse it with similar-sounding phrases. By avoiding these common pitfalls, you can use 'of course' to enhance your English and communicate more clearly and politely.

There are many ways to express agreement or obviousness in English, and choosing the right alternative to 'of course' can make your speech more precise and varied. One of the most common synonyms is 'certainly.' This is slightly more formal and is often used in professional or polite service contexts. If a boss asks if you can finish a project, 'Certainly' sounds very professional and committed. It lacks the 'obviousness' nuance of 'of course,' making it a safer choice if you want to avoid sounding dismissive.

Certainly: More formal and very polite. Great for professional settings.
Naturally: Focuses on the logical or expected nature of a fact.

'Could you sign this?' 'Certainly, where should I sign?'

Another alternative is 'naturally.' This word is very close to the 'obvious' meaning of 'of course.' It suggests that something follows a natural order or logic. 'Naturally, the best students got the highest grades.' It is often used in storytelling or when explaining a process. It sounds a bit more sophisticated than 'of course' and is very common in written English. However, like 'of course,' it can also sound a bit arrogant if used incorrectly.

For casual conversations, 'sure' or 'no problem' are excellent alternatives. 'Can I use your pen?' 'Sure!' or 'No problem!' these phrases are friendly and relaxed. They don't carry the weight of 'obviousness' that 'of course' does, which makes them very safe for everyday use with friends and colleagues. In American English, 'sure' is particularly common and can be used in almost any informal situation to show agreement.

'Want to grab lunch?' 'Sure, that sounds great!'

In more emphatic situations, you might use 'absolutely' or 'definitely.' These words show 100% agreement and are very high-energy. 'Do you think we can win?' 'Absolutely!' These are great for building excitement or showing strong support. They are less about something being 'obvious' and more about your personal conviction. Using a variety of these words will make your English sound more natural and help you express exactly how you feel in any given situation.

Absolutely: Shows very strong agreement and enthusiasm.
By all means: A very polite and formal way to give permission.

'May I ask a question?' 'By all means, go ahead.'

In conclusion, while 'of course' is a fantastic phrase, it's just one tool in your vocabulary. By learning when to use 'certainly,' 'naturally,' 'sure,' or 'absolutely,' you can navigate social situations with more confidence and nuance. Each word has its own 'flavor,' and mastering them all will help you become a more effective and engaging communicator in English.
