watashi mean " i " ex: watashi wa GTO desu --> i am GTO wa to explain that we talk about the subject so it is watashi desu mean like "am" or "are" i am ,,, you are ,, he is .... no it's to link between thing and the other thing for example : kore wa Gto no pasokon desu--> it's the personal computer of GTO kore = this is pasokon=PC(Personal Computer)

this is a structure:watashi"wa"..."desu" it equals to "i'm..." for example:i'm a student, we can say "watshi wa gakusei desu." "watashi no"equals to"my" for example: my mother, we can say "watashi no haha"
