2 Yallah = come on/let's go. This word is a classic favorite-for learners and natives alike! If you visit a country where Arabic is spoken, not a day will go by where you won't hear hurried drivers stuck in traffic screaming, "yallah!". It means, "hurry up," or "let's go.". Of course, you can use it in a variety of ways
Yalla it turns out, is a loanword from Arabic, a portmanteau of ya + Allah, or "oh God" (in Arabic, the "L" sound is more drawn out, and the "ahh" is a bit closer to an "uhh").
