Normally, when someone answers the phone with 'Hello', people can understand them and hear them more clearly, mainly because 'Hello' has two syllables, and 'Hi' has only one. If you were to answer the phone with 'Hi' instead, people might miss what you are saying and ask you to repeat it, if you say 'Hello', it's no bother at all.
Also, if you are answering with 'Hi', it is informal, and you say 'Hello' as a question when picking up the phone, not a greeting as you would say when you see someone you know, because a normal phone conversation will go something like this...
"Hello?"
"Hi, it's ----"
"Oh, Hi ----!"
And you would say something more infomal if it's a friend or a relative or someone you know well.
hello to answer a phone, "hey" otherwise
salut - hi/bye allo - hello when answering the phone
The word "HI" is used more often in conversation. "HELLO" is generally used when they answer the telephone or open the door. "HI" is definitely used more than hello in the USA.
Hello is more formal and Hi is more casual and laidback
Hello
in Jamaica hi is Jambo and jambo translated was hello. Also hi is short for hello. HI! or HELLO!
"Hello" sounds a bit more formal than "hi", but it kind of depends on how you say it. Both "hello" and "hi" can be made more friendly with a smile and a look on your face that shows you are genuinely glad to greet the person.
"Privyet" is a colloquial greeting in Russian. Think of it as someone saying, "Hi!" or "Hey!" in English, rather than the more formal "Zdrasvitsa" ("Hello").
you say hi she says hi then you ask how are you and see where it goes from there
either hello, good day, hi, howdy, g'day mate, or any other form of saying hello. If you want to be rude, then say goodbye, go away, or any other form of telling someone to leave you alone.
hi lol
Hi
