Hello 1- كان = 是 in chinese. Remember something, we don't use "كان" like it uses in English. for example : I am Yusuf ===== أنا يوسف ====== in origine it's like : أنا أكون يوسف [ why it is not using on arabic] because this word means only the existence of something : it can be in the past, present, future, or existence of something in a place. 但是, the real reason which makes "كان" no-usage, because when we say "كان" that means we know, but actually, we are weak and we aren't sure about now, and past and also future, only the God who knows, that's why we say : الله يعلم ما كَانَ وما يكون، ومالم يكن أن لو كَانَ كيف يكون [The God knows what was and what is, and what isn't "exist", and if it was how it is] that means, God is the only one who knows everything, [the existence of everything, and our existence, our future, our past, our present..]. That's why, we don't say " I am Yusuf" in Arabic --------------------------------------------------- when we use "كان" in the past, that means two things : something was in the past, or changing of a situation. [something was in the past] كان في قديم الزمان كان أحمد متزوجا [someone was married, but in the past, and perhaps he doesn't marry][changing of a situation] ------------------------------------------------------------------ تكوين means : إنشاء or means : تدريب for example : [it has created a new society for helping the poor people] قد تم تكوين مؤسسة جديدة لمساعدة الفقراء it has created = قد تم تكوين it has = قد تم created = تكوين قمت بتكوين شامل في اللغة العربية [I did a complete practice in Arabic language] شامل = complete, practice = تكوين

Hi ! كان and تكوين are totally different: كان is a verb that means "was" (past) and تكوين (name) comes from the verb كون (past) يكون (present) and it means "form" so تكوين means "formation" I hope it helps:) have a nice day!
