والله

1. Wallah = I swear/by God
والله

Wallah literally means “I swear to God,” and it is sure to come up in conversation way more times than you can count. Wallah, I promise I’m not lying! If a friend invites you to have dinner with her family and you just can’t get enough of her mom’s delicious cooking, you can say, “wallah, this is the most amazing meal I’ve ever had!” One thing to note: for Muslims, it’s considered a sin to say, “wallah,” if you’re lying.
