1. Hey, Hey man, or Hi
You can use “hey” and “hi” to greet someone instead of “hello”. Both are particularly popular among younger people. While “hi” is appropriate to use in any casual situation, “hey” is for people who have already met. If you say “hey” to a stranger, it might be confusing for that person because he or she will try to remember when you met before! You can also add “man” to the end of “hey” when greeting males. Some people also use “hey man” to casually greet younger women, but only do this if you know the woman very well. Remember that “hey” doesn’t always mean “hello”. “Hey” can also be used to call for someone’s attention.
2.2. How’s it going? or How are you doing?
These are casual ways of asking “how are you?” If you’re trying to be particularly polite, stick with “how are you?” but otherwise, you can use these expressions to greet almost anyone. The word “going” is usually shortened, so it sounds more like “go-in”. You can answer with “it’s going well” or “I’m doing well” depending on the question. Although it’s not grammatically correct, most people just answer “good” – and you can too. Like when responding to “how are you?” you can also follow your answer by asking “and you?”.
3. How’s life? How’s life treating you?
4.How’s your day?
5 Good to see you
6. Long time no see or It’s been a while
13. Are you OK?, You alright?, or Alright mate?
This casual way of asking both “hello” and “how are you” is common in Britain. You can respond “yeah, fine”, or simply “alright”.
16. G’day mate!
This casual greeting is an Australian abbreviation of “good day”. Keep in mind that Australian greetings often use “ya” instead of “you”. So “how are ya?” is the same as “how are you?”, and “how are ya going?” is basically the same as “how’s it going?” or “how are you doing?”
17. Hiya!
This greeting, short for “how are you?”, is commonly used in certain parts of England. However, you don’t need to actually answer this question – you can just say “hey!” right back.
