In conversation and writing, speakers often need to emphasise what they say — to stress that something is true, to confirm strongly, to add weight to a claim. English has many fixed expressions for emphasis. 'Really' (truly) — the most common emphasis word. 'Indeed' (formal confirmation, similar to 'truly'). 'In fact' (in reality — often introducing a stronger or surprising point). 'Absolutely' (completely — strong agreement). 'Definitely' (without doubt — confident confirmation). 'Certainly' (without doubt — slightly more formal). 'Of course' (naturally — agreeing or confirming). 'Without a doubt' (with no uncertainty — strong emphasis). Each is a fixed chunk used at the right register and strength. Students at B1 level often have only 'really' and 'very' for emphasis. Mastering more expressions adds precision and fluency. This lesson covers the main emphasis expressions at B1 level. Connects to opinion expressions (#40), hedging language (#25), and clarifying expressions (#60).
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
The film is really good. (= truly — most common emphasis word)
The film is indeed good. (= as confirmed — formal)
The film is, in fact, good. (= in reality — often before something surprising)
The film is absolutely good. (= completely — strong agreement)
The film is definitely good. (= without doubt — confident)
The film is certainly good. (= without doubt — slightly formal)
The film is, of course, good. (= naturally — confirming the obvious)
All seven add emphasis. What is the difference between them?
Each expression adds emphasis in a slightly different way. 'Really' is the everyday default — truly, genuinely. 'Indeed' is formal confirmation, often used in writing or formal speech. 'In fact' adds a sense of reality, often introducing something surprising or stronger than expected — 'I thought he was unkind. In fact, he is the most generous person I know.' 'Absolutely' means completely, with full agreement. 'Definitely' is confident confirmation. 'Certainly' is similar but slightly more formal. 'Of course' is for confirming the obvious or natural. Each fits a different context. Students who use only 'really' for everything miss the precision available. Adding variety makes their English more natural and adult.
A: A friend asks if you can come to dinner on Saturday. You strongly want to confirm.
B: A teacher asks if education is important. You confirm with formal weight.
C: Someone says your village is small. You correct them — actually it has grown a lot recently.
Which expression fits each: definitely / indeed / in fact?
Each context fits a specific expression. Context A (confirming you can come to dinner): 'definitely' or 'absolutely' fit best. 'Yes, definitely, I will come.' or 'Absolutely, I would love to.' Both confirm strongly with confidence. Context B (confirming education is important — a serious topic, formal context): 'indeed' fits well. 'Education is indeed important — perhaps the most important investment we can make.' The formal 'indeed' fits the serious tone. Context C (correcting someone about village size, introducing surprising information): 'in fact' is exactly right. 'You think the village is small? In fact, it has grown a lot recently.' The 'in fact' introduces the corrective information. Each situation calls for a specific expression.
FORMAL (writing, academic, professional speech):
indeed, certainly, without a doubt
NEUTRAL (works in many contexts):
really, in fact, definitely, absolutely, of course
INFORMAL (casual conversation):
for sure, totally (American)
Which expressions fit which contexts?
Emphasis expressions vary by formality. 'Indeed', 'certainly', and 'without a doubt' are slightly more formal — they fit academic writing, professional speech, and serious contexts. 'Really', 'in fact', 'definitely', 'absolutely', and 'of course' work in many contexts — neutral. 'For sure' and 'totally' are casual — fine in conversation between friends but less appropriate in formal writing. Students should match the expression to the context. A formal essay takes 'indeed' or 'certainly'. A casual chat takes 'really' or 'definitely' or 'totally'. A formal presentation might use 'absolutely' or 'without a doubt' depending on tone. Mixing register sounds wrong — using 'totally' in a formal essay or 'indeed' in casual chat between friends is mismatched.
| Expression | Function | Register | Example |
|---|---|---|---|
| really | Truly, genuinely — most common | Neutral, any context | This food is really delicious. |
| indeed | As confirmed, truly — formal | Formal | Education is indeed the foundation of progress. |
| in fact | In reality — often before surprising or stronger points | Neutral | I thought he was lazy. In fact, he works very hard. |
| absolutely | Completely — strong agreement | Neutral to formal | You are absolutely right about the new policy. |
| definitely | Without doubt — confident confirmation | Neutral | I will definitely come to your party tomorrow. |
| certainly | Without doubt — slightly formal | Formal to neutral | This is certainly the best solution. |
| of course | Naturally — confirming the obvious | Neutral | Of course you can borrow my book. |
| without a doubt | With no uncertainty — strong | Formal to neutral | Without a doubt, this is the right decision. |
| obviously | Clearly — sometimes condescending | Neutral | Obviously, the answer is yes. (be careful — can sound rude) |
NOTE 1 — Match emphasis to context: Different situations need different emphasis. Casual confirmation (yes I will come): definitely, absolutely. Formal statement (education is essential): indeed, certainly. Surprising correction (actually, the opposite is true): in fact. Choose based on the kind of emphasis needed.
NOTE 2 — Match register: Indeed, certainly, without a doubt are formal. Really, definitely, absolutely, in fact are neutral. For sure, totally are casual. Match the expression to the context — academic essay, casual chat, professional speech.
NOTE 3 — Position in sentence: Most emphasis expressions can go in different positions. 'I will definitely come.' 'Definitely, I will come.' 'I will come, definitely.' The middle position (between auxiliary and verb) is most common. Some expressions like 'in fact' and 'of course' are usually at the start or set off by commas.
NOTE 4 — These are fixed chunks: 'In fact' (not 'in the fact'). 'Of course' (not 'of the course'). 'Without a doubt' (with the article 'a'). Students must learn the exact wording. Changing words breaks the expression.
NOTE 5 — Watch for 'obviously': Obviously can sound condescending or rude — implying that the listener should already know. Use carefully. 'Of course' is similar but warmer. For confirming something the listener might not know, use 'in fact' or 'actually' instead of 'obviously'.
Emphasis expressions add fluency and precision to student English. Without them, students sound flat — 'I really like it' for every level of liking. Mastering 5 to 8 emphasis expressions gives students variety and the ability to match emphasis to context. The lesson connects to opinion expressions (#40), hedging language (#25), and clarifying expressions (#60). Together these four lessons cover the main tools for advanced communication: stating views, softening claims, clarifying meaning, and emphasising important points.
Practise emphasis through real conversations. Ask students yes/no questions and require them to confirm with different expressions. 'Will you come tomorrow?' Different students answer with definitely / absolutely / of course / certainly. Real practice builds the chunks into active use.
Choose the best emphasis expression for each context. Think about formality and the kind of emphasis needed.
Each sentence has a problem with an emphasis expression. Suggest a better version and explain.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — Beyond really (5 min): Ask students to add emphasis to a simple sentence using only 'really' and 'very'. Show that this becomes repetitive. Establish that English has many emphasis expressions — each fits a different context.
STEP 2 — Casual emphasis (6 min): Drill the casual emphasis words: really (truly), definitely (without doubt), absolutely (completely), of course (naturally). All work in conversations and informal writing. Practise five examples each.
STEP 3 — Formal emphasis (6 min): Drill the formal emphasis: indeed (formal truly), certainly (formal without doubt), without a doubt (strong formal). Match them to formal contexts — academic essays, professional speech, serious writing. Practise five examples.
STEP 4 — In fact for corrections (5 min): Spend focused time on 'in fact'. It introduces surprising or corrective information. 'I thought he was lazy. In fact, he works very hard.' 'Was the meeting good? In fact, it was excellent.' Practise five examples where 'in fact' adds emphasis through correction or surprise.
STEP 5 — Match emphasis to context (8 min): Give students contexts and ask them to choose the right emphasis expression. Casual chat with friends. Formal email to boss. Confirming RSVP to wedding. Correcting a wrong assumption. Strong agreement. Discuss as a class. The exercise drills register awareness.
