oh ! thank very much !

salamu alakum, the answer is : no, japanese is different from chinese, actually you can say japanese is fluent from chinese language,let me explain well: the japanese use the 3 methods of writing, the gana,kata,and the kanji, the final one "kanji", they use the chinese characters, I meant the traditional characters, that's why you see that japanese and chinese is similar, but for real, they are so different, chinese grammar is easier than japanese, and the pronunciation of japanese is easier than chinese. one thing, the kanji characters haven't the same pronunciation of the chinese characters. but they can have the same meaning.

Natalia you have really added so much info , thank u i am interested in learning Spanish and Japanese,, so i think i will begin with Spanish since i know English and Arabic it will help me in learning it , right ?

thank u all is Chinese similar to Japanese ??

For your other question, well I have been trying to learn 2 languages at the same time, and yes it has been hard but it feels good to know I can do it. I study Hebrew and Arabic and it's not that hard to learn both because both languages are from the Semitic family. They are so familiar, here is example of some words: In Arabic father, mother, son, daughter, brother, sister and house are "Ab, Um, Ibn, Bint, Akh, Ukht, Bayt" and in Hebrew it's " Abba, Ima, Ben, Bat, Akh, Akhot, Bayt" It's also easy for me to learn French, Italian and Portugese because my native language is Spanish. A example to show you is how to say good morning in all these langauges " Bonjour, Boungiorno, Bom dia, Buenos dias" So I think the best way to learn to 2 languages is to study 2 that are related to each other because you first study one and when you study the other one it will help you remember the first one. English is related to Old German, so I could probably learn German, but I think that studying Arabic is enough. I thought I was only going to learn one more language with Arabic, but I ended up learning "El Fos7a, Sham Arabic and El 3miya Masriya. It's too much I feel like I'm studying 3 languages in 1 language LOL! xD
