What does informal tone mean? This means the manner of our speaking and writing when addressing people whom we know personally. It resembles natural speech. Informal tone involves the use of short sentences, conversational language, and personal style. If you have ever texted someone through WhatsApp, you must be familiar with this tone.
Thus, what is an informal tone then? The informal tone in English implies a comfortable tone that precedes any formalities. Here is an example: compare “I would be grateful if you could attend” and “Hope you can make it!” The second sentence sounds like a person you know, whereas the first one is too formal.
At Tiju’s Academy we teach this from day one, because nurses, job seekers, and students all need informal English for speaking just as much as they need formal English for exams.
What Is Informal Tone? A Simple Definition?
The easiest definition of informal tone can be stated like this: language that is conversational and easy, which makes it sound natural when speaking to friends, family members, or colleagues.
It does not mean careless English. It does not mean broken grammar. It means choosing words and sentence patterns that match a relaxed situation. In language teaching, we call this choosing the right register in English. The register refers to how formal you are depending on who you are communicating with and for what reason.
This is an instance of an informal tone in English:
- “Hey, can’t make it tonight. Work has been hectic. Can we catch up this weekend?”
While the same statement in a formal tone would be:
- “I am afraid I will not be able to make it tonight because of work. Maybe we can meet over the weekend?”
The first message has contractions, a sentence fragment and a friendly question. The second sentence is formal, as it has no contractions and is longer and complex. Neither is wrong. They belong in different places.
It’s worth noting at once: tone is what lies behind the choice of register, while register is the level of formality. So the informal language in English in the context of this blog is the casual register along with the friendly tone that accompanies it.
Words That Create Informal Tone? Characteristics With Examples
There are several characteristics that will show that your tone is informal. When you get acquainted with them, you’ll find them in any message, whether it is a text message, a video on YouTube, or the way of speaking of your mates.
The following list contains the main examples of informal tone and their features:
- The use of contractions: don’t, can’t, I’m, we’ve, and it’s. Contractions in formal texts are written without apostrophes.
- Phrasal verbs “pick up,” “hang out,” “put off,” and “get along.” Single verbs are used in formal language, e.g., “collect,” “socialize,” and “postpone.”
- Colloquial expressions and common phrases: “no worries,” “a bit,” “loads of,” and “kind of.”
- Slang and idiomatic expressions “That exam was a piece of cake.” Be careful with such expressions, especially in exams.
- Pronouns “I” and “we” and addressing “you.”
- Short sentences and even sentence fragments. “Loved it. Totally worth it.”
- Exclamation marks and rhetorical questions. “Can you believe it?”
- Everyday vocabulary instead of technical vocabulary. “Get” instead of “obtain.” “Help” instead of “assist.”
- Personal anecdotes and a bit of humor. Stories about your own life are welcome.
To make this easier, here is a short informal tone words list with the formal version next to each one:
| Informal | Formal |
| get | obtain / receive |
| a lot of | a great deal of |
| kids | children |
| ask for | request |
| find out | discover |
| sorry | I apologise |
| thanks | thank you/I appreciate |
| let me know | please inform me |
| about | approximately |
| buy | purchase |
How can one determine whether a piece of writing uses an informal tone or not? Try reading it out loud. If it sounds like something that one would casually say to a friend over a cup of coffee, then the tone is informal; if it sounds more like the kind of notice you would read in the hospital, then it is formal.
It is here that the usefulness of our MORPHOLOGIC classes becomes apparent. Grammar lessons for most students revolve around memorizing rules. In MORPHOLOGIC, grammar lessons take place through oral activities wherein contractions, phrasal verbs, and question formations are learned through practice, not from memorization of tables.
Why Informal Tone Matters in English?
Informal tone is important because most real-life communication is informal: talking to colleagues, responding to your friend or addressing a shop owner. If you cannot speak English in an informal manner, you will appear to be too stiff and formal and people will find it difficult to open up to you.
Here is why conversational tone in writing and speech works:
- You will sound natural. People who use English according to textbooks tend to sound very formal, like a news reporter. With informal tone, you will sound natural.
- You will make connections faster. Warmth comes with casual communication. “How’s it going?” creates a bond but the sentence “How do you do?” will not.
- You will understand other people better. Native speakers use contractions, idioms and phrasal verbs all the time. Knowing those constructions, you will understand movies, phone calls and meetings much easier.
- Your writing will engage readers. An informal tone is typical of blogs, emails to your friends, social media updates and private letters. An informal tone will allow your readers to read longer.
- It gets rewarded in exams. An informal tone is valued by IELTS General Training letter writing task and IELTS speaking exam.
There is a bigger reason too. Confidence. Many students arrive at Tiju’s Academy with strong grammar but freeze in conversation. This is a tone issue, not a grammar issue. They have never spoken the easy English that conversations depend on.
That is why we built BOLDENIUM, our confidence-building session. It is a safe space where students speak without being corrected mid-sentence. The goal is simple: get comfortable being informal in English. Once that fear drops, formal English becomes much easier to add on top.
We also run TALKATHON, which we call the fluency tour. Students have to speak for some minutes about usual topics while going from one interlocutor to another without any preparation. This activity resembles casual conversation at a party. As a result of participating in TALKATHON, contractions and phrasal verbs appear automatically.
How Informal Tone Connects Across the Tiju’s Academy Course
Informal tone is not a single lesson in our spoken English programme. It runs through every module at Tiju’s Academy, the best language academy in Kerala for OET, IELTS, PTE, NCLEX-RN, Prometric, DHA, MOH, HAAD, CBT and German.
Daily speaking practice and live conversation classes
Every student speaks every day. Our live conversation classes are built around real situations, so the informal tone comes naturally. Trainers listen for the small things: contractions, natural questions, whether it sounds like you.
Role plays: interviews, meetings, travel and phone calls
Role plays are where tone switching is trained. You might play a nurse calming a worried patient (warm, informal), then present a handover to a doctor (professional tone). Our interview and workplace English modules use the same method.
Level-based and need-based teaching
Two of our core methods shape how informal tone is taught:
- LEVEL CRAFT TECHNIQUE is our level-based teaching system. The novice learns basic informal greetings and responses. The advanced learner studies idioms, humour and delicate register code-switching. No one is plunged in at the deep end.
- EDUFA is need-based teaching. A nurse preparing for OET and the UK does not need the same informal English as a student heading to Germany for a Master’s degree. EDUFA shapes the vocabulary for daily situations around what you will actually face.
Listening with real accents
You cannot use an informal tone well if you cannot hear it. PHONODIVERSA sessions expose you to British, Australian, American, Irish and Indian accents, because informal speech is faster and more clipped than textbook audio. For deeper sound work, the PHONICS LAB phonetics class is available on demand.
SCREW, our movie time sessions
Films are full of natural, casual English. In SCREW sessions, we watch short clips, pause, pick apart the slang and contractions, and then act the scene out. It teaches more real-world informal English than any textbook page.
Digital learning and WhatsApp assignments
E-FLU is our digital language learning system. Between classes, you get short phone tasks, including WhatsApp voice note assignments, with personalized feedback within a day. Your progress is tracked through LD-360, our assessment and evaluation system.
Individual attention and mentorship
In SINGULARIS every student gets individual attention in a small batch. WISDOMIC mentorship meetings review your speaking samples and set the next target. With TOGETHERIUM, family members can learn together, ideal for couples or parents and children moving abroad.
Games, writing, and public speaking
LINGOX makes informal English fun through games and activities. INKISTA covers basic writing skills, including friendly emails and informal letters. Public speaking practice comes once casual confidence is in place, and OMNITUTORIUM ties everything into one connected programme.
Students who join us for IELTS, OET, or NCLEX-RN coaching often add the spoken English module for exactly this reason. Exams test formal English. Life tests both.
Informal Tone vs Formal Tone: What Is the Difference?
Tone of formality vs. informality depends on the degree of separation. The tone of formality maintains a respectable separation between the speaker/writer and the listener/reader. The tone of informality does away with all such separation and speaks to the audience as a friend. The rest depends on this decision alone.
Here are some comparisons of “informal tone vs. formal tone.”
| Feature | Informal tone | Formal tone |
| Contractions | don’t, I’m, we’ll | do not, I am, we will (no contractions) |
| Vocabulary | everyday words, phrasal verbs | technical vocabulary, single verbs |
| Sentence length | short sentences, fragments | longer, complex sentences |
| Pronouns | I, we, you | often third person or impersonal |
| Voice | active, personal | more passive voice, objective language |
| Feeling | warm, chatty, sometimes funny | neutral, serious, professional tone |
| Punctuation | exclamation marks, questions | full stops, few exclamations |
| Typical use | texts, friendly emails, blogs, speaking | reports, applications, essays, official letters |
Some formal vs. informal English examples in full sentences:
- Informal: “Sorry I missed your call, I was stuck in traffic.” Formal: “I apologise for missing your call; I was delayed by traffic.”
- Informal: “Can you send me the report by Friday?” Formal: “Would you kindly forward the report by Friday?”
- Informal: “The results were pretty good.” Formal: “The results were satisfactory.”
- Informal: “We’re going to look into it.” Formal: “The matter will be investigated.”
Informal vs. formal vs. semi-formal tone
Communication is usually somewhere in between the two extremes.
In terms of tone, semi-formal is polite and not too stiff; you can apply it to emails to your familiar manager, letters to the landlord, messages to the colleague of another department. This tone can include some contractions and is devoid of slang.
A simple tip:
- For friend or relative – informal
- For colleague, teacher, neighbor, landlord – semi-formal
- For employer, hospital, university, government office – formal
Neutral tone lies in between those two and should be used in IELTS Task 2 essays. It is the real art to recognize the level of tone required in each situation and to be able to switch to it. This is called context-appropriate language, and this is what our trainers listen for in each role-play.
Can I Use Informal Tone in IELTS Writing? Informal Tone in IELTS and OET
However, that is only true for one particular section. In the IELTS General Training Task 1 informal letter, informal language is allowed and even encouraged, while in the IELTS Speaking section, the use of informal language will earn you extra points. On the other hand, it is penalized in IELTS Writing Task 2 and OET letters.
IELTS General Training Task 1: the informal letter
In case the question asks you to write a letter to a friend, then the examiner will be expecting you to adopt a more informal style of writing. The following are some tips on how to write an informal letter in the IELTS GT module:
– Begin with “Dear Anu,” or “Hi Rahul,” but never “Dear Sir or Madam”;
– Write a greeting like “Hope you are well!” or “It’s nice hearing from you!”;
– Always use contractions;
– Introduce a personal story or some kind of humor if it is appropriate;
– Make use of phrasal verbs and colloquial language, like “catch up,” “drop by,” “sort out”;
– End with “Take care,” “Love” or “Catch you soon” and your name.
Getting the tone right here counts under the Task Achievement band descriptor. A friendly letter written in a stiff, formal voice loses marks even if the grammar is perfect. This is one of the most common mistakes we correct in our IELTS coaching classes at Tiju’s Academy. Our INKISTA writing sessions include informal letter writing practice with a trainer checking every draft.
IELTS Speaking Part 1: natural responses
The IELTS speaking test involves a discussion. Brief and realistic answers always get high marks rather than well-prepared speeches. “I come from Kochi; it is a very busy port city” will sound much better than “I come from the city of Kochi, which is a very famous port.”
The lexical resource band descriptor rewards idioms used naturally, not forced. Our daily speaking practice and BOLDENIUM sessions are designed for exactly this kind of speech.
IELTS Writing Task 2: why informal is penalised
Task 2 is an essay. It needs a neutral to formal academic tone. Contractions, slang, rhetorical questions, and “you” will pull your score down under lexical resource and task response. Write “do not” instead of “don’t.” Replace “kids” with “children.” Drop the exclamation marks.
OET letter tone: the formal contrast
OET Writing is a referral, discharge, or transfer letter to another healthcare professional. It must be formal, clear, and objective. No contractions, no personal comments, no chatty openings. The nurses who practice informal speech when interacting with us tend to make this mistake because that’s why the OET Writing course helps in switching back into the professional mode by using the case notes. The same is true for the NCLEX-RN, Prometric, DHA, MOH and HAAD tests of clinical English in a formal manner. The German courses cover the “du” and “Sie” division in German.
How to Write in an Informal Tone: A Step-by-Step Guide
Writing in an informal tone is easy once you stop trying to impress and start trying to connect. Picture one real person and write to them. Here is the method we use in class.
- Decide who you are writing to. A friend, a cousin, a classmate. Audience and purpose decide the register.
- Open like a person. “Hi Priya, how’s everything?” beats “I hope this letter finds you well.”
- Use contractions and small words. “I’m” not “I am.” “Buy,” not “purchase.”
- Add a phrasal verb and keep sentences short. “Let’s catch up soon.”
- Talk to the reader. Use “you” and ask a question. Tell one small story.
- Read it aloud. If you would not say it, do not write it.
A before-and-after example from one of our students:
- Before: “I am writing to inform you that I have recently relocated to a new apartment and would like to invite you to visit.”
- After: “Guess what, I’ve finally moved into the new flat! You have to come and see it.”
Same content. Completely different feel.
Is informal tone bad in writing? Only when it is in the wrong place. In a friendly letter, a blog like this one, a WhatsApp message, or a social post, it is exactly right. In an essay, a hospital referral, or a job application, it is a mistake.
This is how our E-FLU tasks are performed: we write an informal message, record it in a voice message format, and receive feedback. Only ten minutes a day, and students see the change within two weeks.
Conclusion
Informal tone is the English of real life. It is how you make friends, calm a patient, settle into a new workplace, and enjoy a film without subtitles. Formal tone is the English of exams and official letters. A confident speaker needs both, and more than that, needs to know when to switch.
That switch is what we teach at Tiju’s Academy. Speaking practice on a daily basis, role-playing, SCREW, TALKATHON, and personalized feedback in small batches provide you with the practical knowledge of conversational English. Our OET, IELTS, PTE, NCLEX-RN, Prometric, DHA, MOH, HAAD, and CBT training include the formal aspect of learning English, using the same trainers and the same progress reports.
