The safest way to greet someone in English is "Hello" — polite and right for almost any situation. With friends, "Hi" and "Hey" feel warmer and more relaxed. Add the time of day — "Good morning" — for a touch more politeness, and you are ready for nearly any greeting.
The tricky part is not the words themselves. It is knowing which one fits the moment, and spotting the greetings that only look like questions. Here is the whole map.
The formality ladder
Most English greetings sit on a simple scale from polite to very casual. When in doubt, move one step up — a slightly formal greeting is never rude, but a very casual one can be.
| Greeting | Formality | When to use it |
|---|---|---|
| Hello | Neutral, polite | Anyone, anywhere — the safe choice |
| Hi | Friendly | Your everyday default with most people |
| Hey | Casual | Friends and people you already know |
"Hey" is warm and common, but with a stranger, a new boss, or an older person it can sound too familiar — a little like walking in without knocking. Save it for people you know.
Good morning, good afternoon, and one big trap
Time-of-day greetings add polish. They are great at work, in shops, and with people you are meeting for the first time.
| Greeting | When |
|---|---|
| Good morning | From waking up until about midday |
| Good afternoon | Midday until early evening |
| Good evening | After dark, at dinner, or formal events |
"Good night" is not a greeting. It is a goodbye — the thing you say when you leave at night or go to bed. If you walk into a room in the evening and say "Good night!", people will think you are already leaving. Use "Good evening" to say hello after dark.
Greetings that aren't real questions
This surprises almost every learner: many English greetings sound like questions but are really just friendly hellos. Nobody expects a full report — a short, upbeat reply is all you need.
| You hear | It means | A natural reply |
|---|---|---|
| How are you? | A friendly hello | "Good, thanks — you?" |
| How's it going? | The same, more casual | "Not bad, you?" |
| What's up? (US) | Very casual hello | "Not much, you?" |
| You alright? / Alright? (UK) | A British hello | "Yeah, you?" |
In the UK, "You alright?" (or just "Alright?") is a normal hello, not concern about your health. The expected answer is a relaxed "Yeah, you?" — not a list of how you actually feel. Answering the question too honestly is the classic giveaway of a new speaker.

Saying goodbye
Greetings and goodbyes travel together, so here are the everyday ways to leave. Like hellos, they range from neutral to very casual.
| Goodbye | Formality | Note |
|---|---|---|
| Bye | Neutral | Works everywhere |
| See you later | Casual | No real time is promised |
| Take care | Warm | Friendly, a little caring |
| Have a good one (US) | Casual | "One" means "day" |
Casual greetings usually come with the body, not just the voice. A small nod, a quick wave, or raised eyebrows naturally goes with "Hey" or "Hi." You do not need a big gesture — a tiny one signals you are friendly and open.
Notice that "See you later" does not mean the speaker will actually see you later that day. It is simply a warm way to part. English is full of these friendly set phrases, and once you spot the pattern, they stop being confusing.
