We just learned a few ways to say hello and goodbye in Arabic, like مرحبًا (mrhaban) and مع السلامة! mae alsalamati.
Sometimes you might want to say good morning, good afternoon, or good night.
Good Morning - صباح الخير (sabah alkhayr) - sounds like sah-bah hoo-l-hay-ree 文A
Good Day - يوم جيد (yawm jahid) - sounds like yaw-m jay-ee-d 文A
Good Evening - مساء الخير (masa' alkhayr) - sounds like mah-sah al-hay-ree 文A
Good Night - طاب مساؤك (taba masawuk) - sounds like tah-bah mah-sah-oo-kah 文A
