Sample formal and informal greeting phrases
Here are some sample formal and informal greeting phrases:
Formal Greetings
Formal greetings are used when the situation calls for politeness, distance, or respect. They are common in interviews, emails, business meetings, first introductions, and service encounters where the relationship is not yet familiar.
- Good morning.
- Good afternoon.
- Good evening.
- How do you do?
- Pleased to meet you / Nice to meet you.
- It’s a pleasure to meet you.
- I hope you’re doing well.
- Greetings.
- Dear Sir/Madam (for letters).
- To whom it may concern (for formal letters).
In spoken English, Good morning, Good afternoon, and Good evening are the safest all-purpose choices. They are neutral, widely understood, and appropriate with strangers, colleagues, teachers, and people in positions of authority. How do you do? is more old-fashioned and is mainly heard in very formal introductions, especially in British English; it is not used as a general conversation starter.
Pleased to meet you and Nice to meet you are standard after an introduction. Both are polite, but Nice to meet you is slightly more common in everyday speech, while It’s a pleasure to meet you sounds a little more formal and deliberate. I hope you’re doing well is common in emails and written correspondence because it opens politely without sounding overly stiff.
For letters and emails, Dear Sir/Madam and To whom it may concern are formulaic openings. To whom it may concern is used when the recipient is unknown, but it can sound impersonal, so many workplaces now prefer a specific name or department when possible.
Informal Greetings
Informal greetings are used with friends, relatives, classmates, and people in relaxed settings. They tend to be shorter, warmer, and more conversational than formal greetings.
- Hi! / Hello! / Hey!
- Morning! (casual for Good morning)
- How are things? / What’s up? / How’s it going?
- What’s new?
- Good to see you / Nice to see you.
- Long-time no see / It’s been a while.
- Yo! / Sup / Hey there!
Among these, Hi and Hello are the most versatile informal greetings. Hey is also very common, especially in conversation between peers, though it can feel too casual in some professional settings. Morning! is a shortened, friendly version of Good morning and is often used between coworkers or acquaintances in relaxed environments.
Questions like How’s it going? and What’s up? often function less as literal requests for details and more as greeting formulas. A short reply such as Good, thanks or Not much is usually enough. What’s new? and It’s been a while are useful when reconnecting after time apart, while Good to see you and Nice to see you signal warmth and familiarity.
Choosing the right greeting
Formal greetings are best in professional or polite settings, while informal greetings are used among friends, family, or casual situations. 1 2 3 4
A useful rule is to match the greeting to the level of familiarity and the setting. In a job interview, Good morning and Pleased to meet you fit naturally. At a café with friends, Hey or What’s up? sounds normal. If the relationship is unclear, a more formal greeting is usually safer because it is less likely to sound too familiar.
Tone matters as much as the words themselves. A phrase that is grammatically correct can still sound wrong if it is too casual for the moment. For example, Yo! and Sup are highly informal and can sound playful, youthful, or even careless depending on the context. By contrast, Greetings is correct but uncommon in everyday conversation, so it may sound theatrical or distant outside written or ceremonial use.
Pronunciation and usage notes
Greeting phrases are often learned first through reading, but in real conversation they depend heavily on rhythm, intonation, and context. How are you? may be a genuine question in one situation and a routine greeting in another. In fast speech, How’s it going? often becomes a quick, compressed phrase, while Nice to meet you is usually spoken clearly and with a friendly rising tone.
In English, some greetings are regional or generational. Yo is strongly associated with casual American speech and pop culture. Sup is a very reduced slang form of What’s up? and is usually limited to highly informal conversation. A learner who wants broad, reliable English coverage gets the most mileage from Hello, Good morning, Nice to meet you, How’s it going?, and It’s been a while.
Common mistakes
One common mistake is using an informal greeting in a formal setting, especially with someone older, a client, or a new professional contact. Another is treating every greeting question as a request for a detailed answer. In many English-speaking contexts, How are you? and What’s up? are social openers, not invitations to explain everything that happened that day.
Another pitfall is overusing extremely informal slang such as Yo or Sup. These can sound unnatural if the speaker is not in the right age group or social setting. The safest strategy is to keep a small set of reliable phrases for formal situations and a small set for casual conversation, then add more regional or slangy expressions only after hearing how native speakers use them.
Quick reference
- Formal: Good morning; Good afternoon; Good evening; Pleased to meet you; It’s a pleasure to meet you.
- Informal: Hi; Hey; What’s up?; How’s it going?; Good to see you.
- Written formal: Dear Sir/Madam; To whom it may concern.
Simple greeting phrases are often the fastest way to sound natural at the start of a conversation, and frequent spoken practice helps them become automatic more quickly than passive study alone.
