Far back in human history, you never knew who was trying to kill you and who wasn't. So the practice began of lifting your sword hand up near your head to indicate that you weren't about to draw your sword. Today, this has eveolved into the military salute. For those who didn't or couldn't salute, a greeting was substituted. Today, this greeting is either hello or hi.
They say that to greet each other.
They wave and say Hi!
they say hi and they wonder the woods and discover each other
That means either your both are being friendly or you like each other.
The Assamese people greet each other with 'Nomoskar'
Scotland is the country, the citizens are called Scottish or British since Scotland is part of the United Kingdom. English is also the main language in Scotland which means if two Scotland people wanted to say hi to each other they would say it the same way as any other English speaking person: Hi, Hello or Hey.
The Miwok people traditionally greeted each other with "Haro" or "Haho," both of which can be used to say "hello."
say hi sweetly then say wanna talk the get to know each other soon you'll be bffl/bff
Yes hi is a word because you can say it and other people say it and you can spell it.
Young people will just say Hi and older people Hello
People say hi for traditions and to greet other people. It is used as a slang for the word hello.
They are both words for greeting each other, but hello is more formal. If you were talking to somebody who is stuck up, you say "hello". If you are talking to one of your friends or parents or somebody you've known for a while, you can say "hi".
