Formal:
* أهلاً وسهلاً (Ahlan wa sahlan): This is the most formal greeting, meaning "Welcome." It's appropriate for all occasions, especially when addressing someone older or of higher status.
* صباح الخير (Sabah al-khayr): This means "Good morning" and is used in the morning.
* مساء الخير (Masaa al-khayr): This means "Good evening" and is used in the afternoon and evening.
Informal:
* سلام (Salam): This means "Peace" and is a very common greeting, used between friends and family.
* شلونك (Shloonak): This means "How are you?" and is used when you want to be a bit more friendly and casual.
* شو اخبارك (Shu akhbarak): This also means "How are you?" and is a more informal way to ask.
It's important to note that:
* In Jordanian Arabic, it's common to use the word "ya" before the greeting, such as "ya ahlan wa sahlan" or "ya sabah al-khayr".
* The tone of voice and body language can also play a role in how the greeting is interpreted.
So, when in doubt, using "Ahlan wa sahlan" is always a safe bet.
