How do say hello in Newcastle?

There's no specific, unique way to say hello in Newcastle. People in Newcastle, like most people in the UK, typically use the standard greetings:

* Hello

* Good morning/afternoon/evening

* How are you?

However, if you want to sound a little more "local," you could use:

* Alright, pet? (This is a common way of saying "hello" in the North East of England, but it can be considered quite informal.)

It's important to note that the use of these greetings might vary depending on the context and the person you are talking to. For example, you wouldn't use "Alright, pet?" when talking to a stranger or in a formal setting.

Ultimately, the best way to greet someone in Newcastle is simply to be polite and friendly.
