Thank you! I'll add this to the product page too:
日本語を勉強しています。話しかけて下さい。
nihongo o benkyou shite imasu. hanashi kakete kudasai.
Japanese language - (direct object marker) - studying. address me - please
I am studying Japanese. Please speak to me.
話しかける means to address someone, start a conversation, start speaking to someone.
For your other question, do you mean 日本語? Japanese language: 日本 (nihon/Japan) 語 (go/language). 日本 literally means 'sun's origin'--the rising sun.
