To say "hi" in Arabic, some common and simple ways are:
- MarHaba (مرحباً): This means "hello" or "welcome" and is used in both formal and informal settings across many Arabic-speaking countries.
- Ahlan (أهلاً): This is another casual way to say "hi" and is often used in informal settings.
- As-salamu alaykum (السلام عليكم): This is a formal greeting meaning "peace be upon you," often used among Muslims and considered polite and respectful.
- Salam (سلام): A shorter, informal version of As-salamu alaykum, simply meaning "peace."
If greeted with "As-salamu alaykum," the common response is "Wa alaykum as- salam" (و عليكم السلام), meaning "And peace be upon you." So for a simple "hi," the easiest is to say either "MarHaba" or "Ahlan." All these are widely understood and used throughout Arabic-speaking regions.
