Introductions – Formal and Informal
Learn how to introduce yourself naturally, choose the right level of formality, and adapt your introduction to classmates, teachers and professional guests.
Formal, Professional and Informal: What Is the Difference?
Formal and professional are not synonyms. They often overlap, but they describe different dimensions of language.
Professional = how appropriately and effectively the language communicates within a workplace or academic context.
FORMAL
Focus: degree of formality, officialness and social/institutional distance.
Question: “Does this sound appropriately formal?”
PROFESSIONAL
Focus: context, purpose, clarity, courtesy and professional expectations.
Question: “Is this appropriate for this professional situation?”
INFORMAL
Focus: relaxed, conversational interaction, usually with people we know well.
Question: “Am I speaking naturally with someone I know?”
Quick Comparison: Formal vs Professional
Remember: Formal describes the degree of formality; professional describes appropriateness for a workplace or academic context.
| Formal Register | Professional Register |
|---|---|
| Focus: official, respectful, more distant | Focus: appropriate, clear, courteous and work-oriented |
| Sounds: more formal or institutional | Sounds: natural but appropriate for work/study |
| Example: “I would be grateful if you could provide the revised document.” | Example: “Could you please send me the revised document?” |
| Key question: “How formal does this need to sound?” | Key question: “Is this appropriate for this professional situation?” |
Same Meaning, Different Register
Here the meaning and purpose stay the same. Only the register changes.
| Context / Meaning | Informal | Professional | Formal |
|---|---|---|---|
| Ask someone to send a file | “Can you send me that file?” | “Could you please send me the revised file?” | “I would be grateful if you could provide the revised document.” |
| Ask for lecture notes | “Sir, can you send me the notes?” | “Professor, could you please share the Unit 3 notes?” | “Dear Professor, I would be grateful if you could provide the lecture materials for Unit 3.” |
| Ask about a meeting | “When are we meeting?” | “Could you please confirm the meeting time?” | “I would appreciate it if you could confirm the scheduled time of the meeting.” |
| Ask someone to finish a task | “Can you finish this today?” | “Could you please complete this by today?” | “I would be grateful if you could complete the task by the end of the day.” |
Same Context, Different Register
The purpose remains the same, but the register changes.
Same Context: Requesting Lecture Notes
“Hi sir, I need the notes. Can you send them?”
“Dear Professor, could you please share the lecture notes for Unit 3?”
“Dear Professor, I would be grateful if you could kindly provide the lecture materials pertaining to Unit 3.”
FORMAL = degree of formality
PROFESSIONAL = appropriateness to a professional context
INFORMAL = relaxed, conversational interaction
Key sentence: “Professional language can be formal, but professional does not always have to be highly formal.”
Learning Outcomes
By the end of the lesson, students will be able to:
1. Choose the Right Register
The same person may introduce themselves differently depending on the relationship, purpose and setting.
| Situation | Register | Typical opening | Focus |
|---|---|---|---|
| Meeting a new classmate | Informal | “Hi! I’m …” | Friendly, natural, personal |
| Meeting a project partner | Friendly / collaborative | “Hi, I’m … Nice to meet you.” | Common interests and teamwork |
| Meeting a professor | Formal | “Good morning, sir/ma’am. My name is …” | Respectful and concise |
| Meeting an industry guest | Professional | “Good afternoon. My name is …” | Studies, interests and goals |
| Placement / interview setting | Formal + professional | “Good morning. I’m …” | Relevant education, strengths and goals |
2. Model Introductions
Notice how the information and language change with the situation.
Meeting a new classmate
Introducing yourself to a professor
Meeting a professional guest
3. Build Your Introduction
Use this simple structure rather than memorising a long paragraph.
“I’m …”
“I’m studying …”
“I’m interested in …”
“I hope to …”
“Nice to meet you.”

4. Classroom Activities
Two focused activities move students from controlled practice to spontaneous speaking.
Say it for the situation
Time: 15 minutes
- Students prepare one basic self-introduction.
- The teacher announces a situation: classmate, professor or professional guest.
- Students change their opening, vocabulary and level of detail.
- Partners identify whether the register is appropriate.
Meet, introduce, respond
Time: 20 minutes
- Students work in pairs and introduce themselves for 30–45 seconds.
- Partner asks one follow-up question.
- After each round, students change partners.
- Final round: teacher assigns a formal or professional context.
5. Short Student Self-Introduction Demonstrations
Listen to real student introductions in English and notice the information, sequencing and personal details used by the speakers.
Hector — Student Self-Introduction
Hector introduces himself, explains where he is from and lives, talks about his interests and studies English, and mentions a future study goal.
Teacher prompt: “What information does Hector include? Which details would be useful in a first-day college introduction?”
Zhang Wei / Jason — Student Self-Introduction
A student introduces himself, gives personal information and interests, and connects an interest in mobile technology with future plans.
Teacher prompt: “What makes this introduction personal and memorable? Which detail could you add to your own introduction?”

6. Speaking Assessment — 10 Marks
A quick formative assessment for the final 7 minutes of the lesson.
| Criterion | 2 marks | 1 mark | 0 marks |
|---|---|---|---|
| Register | Consistently appropriate | Minor mismatch | Inappropriate |
| Content | Relevant and complete | Some details missing | Very limited |
| Fluency | Clear, natural flow | Some hesitation | Frequent breakdowns |
| Pronunciation | Clear and understandable | Some errors | Often unclear |
| Interaction | Responds and connects well | Basic response | Little interaction |
Prepare Your 30-Second Introduction
Write keywords, not a complete script. Then speak naturally.
30-Second Challenge
Introduce yourself to a partner. The teacher then announces informal, formal or professional. Repeat your introduction and adapt it to the new situation.
