English is not just about words and grammar—it’s about people. In this unit, we focus on some of the most common and socially important language functions: saying hello, introducing yourself, and interacting politely. You’ll learn how to greet others in both formal and informal situations, introduce yourself and others, and take leave in a polite and natural way.
We’ll also explore polite expressions, cultural norms of politeness, and the appropriate use of titles like Mr., Ms., or Dr. You'll practice responding to common questions such as “Where are you from?” or “How are you?”, and understand the social conventions behind them. Whether you're meeting someone for the first time or saying goodbye after a meeting, this unit will help you make a positive impression and communicate with ease in everyday situations.

3.1 FORMAL AND INFORMAL GREETINGS
Objective:
To recognize and appropriately use formal and informal greetings in different contexts, both spoken and written.
👋 WHAT IS A GREETING?
A greeting is a polite expression used when you meet someone. The form of the greeting depends on:
The relationship (friend, colleague, stranger)
The setting (professional, casual, social)
The time of day

🔹 1. FORMAL GREETINGS
Used in professional settings, with strangers, or when showing respect (e.g., to elders, clients, or superiors).
🔸 COMMON FORMAL GREETINGS:
Greeting    Use Case
Good morning    Before 12 p.m.
Good afternoon    From 12 p.m. to 6 p.m.
Good evening    After 6 p.m. (not “good night”)
How do you do?    Very formal, often first-time meetings
It’s a pleasure to meet you    Business or ceremonial contexts
✅ Example:
Good morning, Mr. Thompson. It’s a pleasure to meet you.

🔸 FORMAL RESPONSES:
Greeting    Typical Response
Good morning    Good morning
How do you do?    How do you do
Nice to meet you    Nice to meet you, too
⚠ Good night is not a greeting. It’s a farewell used before going to sleep.

🔹 2. INFORMAL GREETINGS
Used with friends, family, colleagues, or in casual settings.
🔸 COMMON INFORMAL GREETINGS:
Greeting    Use Case
Hi    Neutral and informal
Hey    Very casual
Hello    Neutral, slightly formal
What’s up?    Slang/informal (U.S. English)
How’s it going?    Casual, friendly
✅ Example:
Hey, how’s it going?
Hi Anna! Good to see you again.

🔸 INFORMAL RESPONSES:
Question    Response
What’s up?    Not much / All good / Same old
How’s it going?    Pretty good / Not bad / Great!
Hi / Hey    Hi! / Hey! / Hello!

🧠 GREETING ETIQUETTE BY CONTEXT
Context    Suggested Greeting
Job interview    Good morning, nice to meet you
New neighbor    Hello, I’m [Name]. Nice to meet you.
Close friend    Hey! What’s up?
Business email    Dear Mr./Ms. [Last Name], Good morning

🗣️ PRONUNCIATION TIP
In spoken English, greetings often include linking and reduction:
How are you? → /ˈhaʊə ju/ or /haʊərjə/
What’s up? → /wʌtsʌp/
Good morning → /ɡʊd ˈmɔːnɪŋ/ (not /gu:d/)

❗ COMMON MISTAKES
Mistake    Correction
Using “Good night” as a greeting    Use “Good evening” instead
Mixing formal/informal phrases    Match tone with context
Translating directly (Buenos días = Good days)    Say “Good morning” instead

3.2 INTRODUCING YOURSELF AND OTHERS
Objective:
To confidently introduce yourself and other people in English, using appropriate expressions for both formal and informal contexts.

👤 INTRODUCING YOURSELF
When meeting someone for the first time, use a greeting followed by your name and sometimes extra personal information like where you’re from or your profession.

🔹 COMMON PHRASES:
Level    Example Phrases
Formal    Hello, my name is...
    Nice to meet you.
    I’m pleased to meet you.
Informal    Hi, I’m [Name].
    Hey, I’m [Name], nice to meet you.
Very casual    I’m [Name], what’s your name?
✅ Example:
Hello, my name is Ana García. I’m from Madrid.
Hi, I’m Alex. I work in tech.

🧑🤝🧑 INTRODUCING OTHERS
When introducing people to each other, it's important to say both names and offer some brief context.

🔸 FORMAL SITUATIONS
Example
Mr. Smith, this is Dr. Johnson.
Let me introduce you to our manager, Ms. Taylor.
I'd like you to meet our new colleague.

🔸 INFORMAL SITUATIONS
Example
This is my friend Laura.
Hey, meet my cousin Tom.
Guys, this is Maria—she’s new here.
✅ Response from the person being introduced:
Nice to meet you.
It’s a pleasure.
Hi, I’ve heard a lot about you!

🧠 USEFUL STRUCTURES
Structure    Example
I’m [name]    I’m Carlos.
I’m from [city/country]    I’m from Buenos Aires.
I work as a [job] / I’m a [job]    I work as a lawyer. / I’m a teacher.
This is [name]    This is my sister, Marta.
Let me introduce you to [name]    Let me introduce you to our director.

📘 CULTURAL TIP
In English-speaking cultures, introductions often include:
A firm handshake (in formal situations)
A smile and eye contact
Sometimes small talk (weather, travel, job)

❗ COMMON MISTAKES
Mistake    Correction    Why?
I am called Juan.    My name is Juan. / I’m Juan.    “I’m called…” sounds awkward
He is my friend the Pedro.    This is my friend Pedro.    No article “the” before names
Let me to introduce you…    Let me introduce you…    “Let me” is followed by base verb

🗣️ PRONUNCIATION TIPS
My name is → /maɪ ˈneɪm ɪz/
Nice to meet you → /naɪs tə ˈmiːt ju/
Let me introduce you → /ˈlet mi ˌɪntrəˈdjuːs ju/
Use linking and reduced forms to sound natural.

3.3 SAYING GOODBYE AND TAKING LEAVE
Objective:
To learn appropriate expressions for saying goodbye in English in both formal and informal contexts, including common phrases for ending conversations politely.

👋 WHAT DOES IT MEAN TO “TAKE LEAVE”?
In English, “taking leave” refers to ending a conversation or interaction in a polite way. It’s not just about saying "bye" — it can include:
Expressing gratitude
Making future arrangements
Wishing someone well

🔹 1. INFORMAL GOODBYE EXPRESSIONS
Used among friends, family, and peers.
Expression    Use Case
Bye    Very common and neutral
See you (later/soon)    Short-term or casual plans
Take care    Polite and warm
Catch you later    Slang, casual
I’ve got to go    Used to exit the conversation
Talk to you soon    For ongoing contact
✅ Example:
Bye, talk to you tomorrow!
I’ll catch you later—gotta run!

🔸 2. FORMAL AND POLITE LEAVE-TAKING
Used in professional settings, with strangers, or in business communication.
Expression    Use Case
Goodbye    Neutral formal farewell
It was a pleasure meeting you    Polite for first meetings
I look forward to seeing you    Polite, positive, forward-looking
Have a nice day/weekend/evening    Common polite phrase
I’m afraid I have to go now    Very formal and soft
I’ll be in touch / We’ll talk soon    For future follow-up

🧠 CULTURAL TIPS
In English, brief goodbyes are typical; you don’t need long farewells.
Politeness is key, especially in formal contexts.
Adding a smile, a handshake, or a friendly tone improves the impression.

❗ COMMON ERRORS 
Mistake    Correction    Why?
Good night at the start of a meeting    Use Good evening    "Good night" = final farewell only
I see you later    See you later    Drop the subject “I” in this case
I’m going to go (as a goodbye)    I’ve got to go / I’d better go    More natural, idiomatic English

🗣 PRONUNCIATION NOTES
See you later → /ˈsiː jə ˈleɪtə/
Take care → /teɪk ˈkeə/
Gotta go → /ˈɡɒtə ˈɡəʊ/ (informal, contracted speech)

💬 EXAMPLE DIALOG
Emily: Well, I should probably get going—it’s getting late.
Daniel: Yeah, same here. It was really great catching up with you.
Emily: Likewise! Let’s grab coffee next week if you’re free.
Daniel: Absolutely. I’ll message you tomorrow to set a day.
Emily: Perfect. Take care and have a great evening!
Daniel: You too! Bye!

3.4 COMMON POLITE EXPRESSIONS
Objective:
To learn and use everyday polite expressions that help maintain courteous and respectful communication in English, both in social and professional settings.

🎩 WHY USE POLITE EXPRESSIONS?
Politeness is a fundamental part of English-speaking cultures. It helps:
Show respect and consideration
Soften requests and refusals
Maintain positive social and professional relationships
Using polite expressions correctly improves your tone, avoids sounding rude, and makes you more effective in conversation.

🔹 BASIC POLITE EXPRESSIONS
Situation    Expression
Requesting something    Could you please…? / Would you mind…?
Thanking someone    Thank you. / Thanks a lot. / Much appreciated.
Responding to thanks    You’re welcome. / No problem. / My pleasure.
Apologizing    I’m sorry. / I apologize. / Excuse me.
Interrupting    Sorry to interrupt, but… / May I ask…?
Asking again    Could you repeat that, please? / Pardon?
Offering help    Can I help you? / Would you like some help?
Ending politely    It was nice talking to you. / Have a great day.

🔸 SOFTENING LANGUAGE
Instead of giving direct commands or refusals, English speakers often use modal verbs, indirect forms, and softening phrases.
Direct    Polite/Softened Version
Close the door.    Could you close the door, please?
I don’t understand.    I’m not quite sure I understand.
That’s wrong.    I think there might be a mistake.
No.    I’m afraid I can’t. / I’d rather not.

🧠 CULTURAL INSIGHT
Politeness in English often uses indirectness: saying things less directly to avoid offense.
“Please”, “thank you”, and “sorry” are used more frequently than in Spanish.
Overuse is rarely a problem; underuse can seem rude or cold.

❗ COMMON ERRORS 
Mistake    Correction    Why?
Give me the pen.    Could you give me the pen, please?    Too direct
Repeat again!    Could you repeat that, please?    Polite form + correct structure
Sorry, what? (too abrupt)    Sorry, could you say that again?    Softer, more natural

🗣 PRONUNCIATION NOTES
Could you… → /kʊdʒə/ (often contracted in speech)
Would you mind… → /wʊdʒə ˈmaɪnd/
Excuse me → /ɪkˈskjuːz mi/ or /ɪkˈskjuːz mə/

💬 EXAMPLE DIALOG
Receptionist: Good morning! How can I help you today?
Client: Good morning. I’m here for a meeting with Mr. Richards. Would you mind letting him know I’ve arrived?
Receptionist: Of course. Could you please take a seat while I notify him?
Client: Certainly. Thank you very much.
Receptionist: You’re welcome. He’ll be with you shortly.

3.5 USING TITLES AND FORMS OF ADDRESS
Objective:
To understand how to use names, titles, and forms of address appropriately in English depending on the level of formality, cultural context, and relationship between speakers.

🎓 WHAT ARE FORMS OF ADDRESS?
Forms of address refer to how you speak to or refer to someone in direct communication. This includes:
•    Titles (Mr., Ms., Dr., etc.)
•    First names
•    Last names
Honorifics or professional roles
Choosing the right form is important for showing respect, formality, and social awareness.

🔹 COMMON ENGLISH TITLES
Title    Use Case
Mr.    Adult men (neutral or formal) → Mr. Smith
Ms.    Adult women (neutral; marital status unknown)
Mrs.    Married women (traditional) → Mrs. Johnson
Miss    Unmarried young women (less common today)
Dr.    Doctors (medical or academic)
Prof.    University professors
Sir / Ma’am    Very formal / respectful → Yes, sir
✅ Use a title + last name in formal situations unless told otherwise.

🔸 FIRST NAME VS. LAST NAME
Situation    Preferred Address
Formal (first contact, workplace)    Mr./Ms. + Last Name
Informal (friends, colleagues)    First Name
Very casual or social    Nickname (if appropriate)
✔ Hello, Mr. Peterson. It’s a pleasure to meet you.
✔ Hi John, how are you?
⚠ Do not use someone's first name in a professional setting unless they invite you to do so.

🧠 SPECIAL NOTES
In emails:
Dear Mr. Brown → formal
Hi Sarah → informal
Use Ms. if you don’t know a woman’s marital status — it’s the safest and most respectful default.
In some cultures (e.g., the US), switching to first names happens quickly. In others (e.g., UK, India), more formality is maintained.

❗ COMMON MISTAKES
Mistake    Correction    Why?
Hello Miss Laura    Hello Ms. Martínez or Hello Laura    Avoid using “Miss” with first name
Good morning teacher!    Good morning, Mr./Ms. [Last Name]    Use proper title in formal setting
Doctor John (unless invited)    Dr. Smith    Use last name with professional title

🗣 PRONUNCIATION NOTES
Mr. → /ˈmɪstər/
Ms. → /mɪz/
Mrs. → /ˈmɪsɪz/
Dr. → /ˈdɒktər/ (BrE) /ˈdɑːktər/ (AmE)

💬 EXAMPLE DIALOG
Receptionist: Good afternoon. Welcome to Lincoln Consulting.
Visitor: Good afternoon. I’m here to meet Dr. Grant.
Receptionist: Of course. May I ask your name, please?
Visitor: Certainly. I’m Mr. Ortega, from Zenith International.
Receptionist: Thank you, Mr. Ortega. Please have a seat while I let Dr. Grant know you’ve arrived.
Visitor: I appreciate it.

3.6 ASKING AND ANSWERING BASIC QUESTIONS (NAME, AGE, NATIONALITY)
Objective:
To be able to ask and answer simple personal questions related to identity, age, and origin, using correct grammar and polite forms.

❓ ASKING FOR BASIC INFORMATION
These are among the first questions exchanged when meeting someone new. The goal is to gather personal but non-intrusive information in a polite and friendly way.

🔹 1. ASKING AND SAYING NAMES
Question    Answer Example
What’s your name?    My name is Laura. / I’m Laura.
How do you spell your name?    It’s L-A-U-R-A.
In formal contexts:
→ May I have your name, please?
→ Could you tell me your full name?

🔹 2. ASKING AND SAYING AGE
Question    Answer Example
How old are you?    I’m 25 years old. / I’m 25.
•    Formal alternatives are uncommon; this question can feel too direct in some cultures. Use only when appropriate.
✅ Optional phrase: If you don’t mind me asking…

🔹 3. ASKING AND SAYING NATIONALITY
Question    Answer Example
Where are you from?    I’m from Mexico.
What’s your nationality?    I’m Spanish.
What country are you from?    I’m from Colombia.
“Where are you from?” is more common and conversational.
“What’s your nationality?” is more formal or used in official documents.

🧠 SENTENCE STRUCTURE RECAP
Function    Structure
Asking    Wh-word + auxiliary + subject + verb
Answering    Subject + verb + complement
What’s your name? → My name is John.
Where are you from? → I’m from Brazil.
How old are you? → I’m 28.

❗ COMMON ERRORS 
Mistake    Correction    Why?
Which is your name?    What’s your name?    “Which” = limited options
I have 30 years    I’m 30 years old    Use verb “to be”, not “have”
I am of Spain    I’m from Spain / I’m Spanish    Literal translation error

🗣 PRONUNCIATION NOTES
What’s your name? → /wɒts jɔː ˈneɪm/
Where are you from? → /ˈweə rə ju frɒm/
How old are you? → /haʊ ˈəʊld ə ju/
Note: “are you” often contracts to /ə ju/ in natural speech.

💬 EXAMPLE DIALOG
Isabella: Hi there! I’m Isabella. What’s your name?
Alex: I’m Alex. Nice to meet you!
Isabella: Nice to meet you too. Where are you from, Alex?
Alex: I’m from Canada, but I’ve been living in Spain for three years. And you?
Isabella: I’m Spanish, from Valencia. By the way, how old are you?
Alex: I’m 27. And you?
Isabella: I’m 29. So we’re pretty close in age!

3.7 USING “NICE TO MEET YOU”, “HOW ARE YOU?” AND VARIANTS
Objective:
To understand and use common social phrases such as “Nice to meet you” and “How are you?” appropriately in greetings and introductions, including variations for different levels of formality.

🗨️ 1. “NICE TO MEET YOU” – WHEN AND HOW TO USE IT
This phrase is used when meeting someone for the first time. It expresses a positive attitude and helps make a polite first impression.
Situation    Typical Use
First-time meeting    Nice to meet you. / It’s a pleasure to meet you.
In reply    Nice to meet you too. / Likewise.

✅ Examples:
Hi, I’m Olivia.
Nice to meet you, Olivia. I’m Marcus.
Nice to meet you too.
⚠ Don’t use this phrase if you’ve already met the person before. Use “Nice to see you again” instead.

🤝 VARIANTS AND FORMAL ALTERNATIVES
Neutral/Formal    Very Informal
It’s a pleasure to meet you.    Good to meet you.
Pleased to meet you.    Great to meet you.
Nice meeting you. (at the end)    Nice seeing you. (informal close)

💬 2. “HOW ARE YOU?” – POLITE SMALL TALK
A very common follow-up greeting in both formal and informal English.
Question    Common Responses
How are you?    I’m fine, thanks. / I’m good. / Not bad.
How’s it going?    Pretty good. / Great. / Same as always.
How are you doing?    Doing well, thanks. / I’m okay.

✅ It's often a social routine, not always a literal inquiry.
It’s polite to ask back:
→ How are you? → I’m good, thanks. And you?

🔁 FOLLOW-UP QUESTIONS
After exchanging greetings, you can ask:
How was your weekend?
How’s your day going?
What have you been up to?
These encourage conversation beyond hello, especially in friendly or workplace settings.

❗ COMMON MISTAKES
Mistake    Correction    Why?
Nice to meet you again!    Nice to see you again!    “Meet” = first time only
How are you? Good. (no subject)    I’m good.    Complete structure preferred
How do you do? (as a reply)    How do you do. (Not a question in this case)    Formal greeting exchange

🧠 CULTURAL NOTE
In English, greetings like How are you? are often ritualized.
Even if you're not “great”, it’s normal to answer with something positive or neutral in public settings.
Save personal honesty for close friends.

🗣 PRONUNCIATION TIPS
Nice to meet you → /naɪs tə ˈmiːtʃu/
How are you? → /ˈhaʊ ər ju/ → /ˈhaʊə ju/
I’m good, thanks. And you? → /aɪm ɡʊd θæŋks ən ju/

💬 EXAMPLE DIALOG
Claire: Good afternoon! I’m Claire Bennett.
Daniel: Hello Claire, I’m Daniel Morgan. Nice to meet you.
Claire: Nice to meet you too, Daniel. How are you?
Daniel: I’m doing well, thanks. And you?
Claire: I’m fine, thank you. It’s a pleasure to be here.
Daniel: Likewise. I hope we’ll have time to talk more during the break.

3.8 CULTURAL DIFFERENCES IN POLITENESS
Objective:
To recognize and understand how politeness norms in English may differ from those in Spanish-speaking cultures, and how to adapt your communication style to avoid misunderstandings.

🌍 WHY CULTURAL POLITENESS MATTERS
What is considered polite or impolite varies between cultures. In English-speaking societies, indirectness, softened language, and ritual expressions often signal respect and social competence.
Understanding these differences helps:
Avoid sounding too blunt or too formal
Build better cross-cultural relationships
Interpret the real meaning behind phrases

🧭 KEY DIFFERENCES IN POLITENESS NORMS
🔹 1. DIRECTNESS VS. INDIRECTNESS
Spanish Norm    English Equivalent
¿Qué quieres? (direct)    Would you like something to drink? (indirect)
Dame eso.    Could you pass me that, please?
No puedo.    I’m afraid I can’t. / I’d rather not.
In English, directness may come across as rude, especially in formal situations.

🔹 2. USE OF "PLEASE", "THANK YOU", AND "SORRY"
English uses these markers of politeness more frequently:
Please is expected in almost any request, even with close friends.
Thank you is often used after routine exchanges:
→ Thanks after receiving change at a store.
Sorry is used not only for guilt, but also to express empathy, interrupt, or ask to repeat something.

🔹 3. TONE AND FACIAL EXPRESSION
English relies heavily on tone of voice to express warmth or distance.
A smile is often used to soften direct speech.
Neutral tone + direct words = may sound cold or aggressive in English.

🔹 4. SMALL TALK AND PERSONAL SPACE
English speakers often use small talk to create comfort before getting to the point.
Questions about age, salary, family situation may be perceived as too personal early in the relationship.

🧠 COMMON MISUNDERSTANDINGS FOR SPANISH SPEAKERS
Behavior    Misinterpretation in English
Being too direct    Seen as rude or demanding
Not using "please" or "thank you"    Seen as disrespectful or unfriendly
Refusing invitations too bluntly    Could offend unintentionally
Using "Do you want…?" with strangers    Sounds too abrupt or pushy
✔ Better: Would you like…?, Do you feel like…?, Shall we…?

🔧 ADAPTING TO ENGLISH POLITENESS
Use softeners: a bit, perhaps, I think, would you mind…
Include social niceties: How are you?, Have a nice day
Mirror the tone and formality of the other speaker
Observe context and adjust level of indirectness

💬 EXAMPLE DIALOG
Lucía: Hello. I need to speak to your manager.
Receptionist: Of course. May I ask what it’s regarding?
Lucía: It’s about a billing issue. I’m really upset, and I want this fixed now.
Receptionist: I understand your frustration, and I’ll do my best to help. Would you mind waiting a few minutes while I contact him?
Lucía: Sure, sorry—I didn’t mean to be rude. I just wasn’t expecting this problem.
Receptionist: No problem at all. Thank you for your patience.
