"Hello" in Dutch is "hallo" or "hoi".
In Dutch, "hoi" and "hallo" are both used as greetings, but there is a subtle difference in their formality and usage.
"Hoi" is a more informal greeting and is commonly used among friends, family members, and peers. It is similar to the English greeting "hi" and is often used to express familiarity, friendliness, or enthusiasm. It's not typically used in more formal situations or when addressing people you don't know.
"Hallo", on the other hand, is a more formal and polite greeting that can be used in both formal and informal situations. It's similar to the English greeting "hello" and is often used when addressing someone you don't know, or in more formal settings such as a job interview or a business meeting. "Hallo" can also be used as a more general greeting, and can convey a sense of respect or politeness.
There is a more formal way to say hello in Dutch. The word for "hello" in formal situations or when addressing someone you don't know is "goedendag" or "goedendag meneer/mevrouw" (good day/sir/madam). Another formal greeting is "dag" (day), which can also be used as a farewell.
