Hi The subject or title of your entry is a bit hard to understand! Let me translate what you said "My friends is Iranian, are they ready??? We want to learn languages!" I guess you meant this: "My Iranian friends, are you ready??? دوست های ایرانی من،(آیا) آماده هستید ؟ It's pinglish: Doost haye Iraniye man,(aya)amade hastid??? "Aya" is optional. You can either use or not use it. But when you don't use "aya" for making questions you have to say the sentence with rising intonation. In the above sentence put a bit stress on "hastid". About the second sentence, as you mentioned you wanted to say "Let's learn Languages together." The translation is exactly what Hoda said: بیایید با هم زبان یاد بگیریم But I want to add some more explanations. “Let’s” means "بیایید" but "بیایید" is formal. You can use it in writings. In daily conversations and for informal usage you can use "بیاین" instead. Now it's your turn,correct my comment!

بیایید با هم زبان یاد بگیریم / biayid ba ham zaban yad begirim/ is correct translation of "Let's learn languages together!" what about a Persian poem to surprising your girlfriend? ;)

impress ur girlfriend with ur ability to speak persian or what?
