I want to known if I got this sentence right. I'm learning the words from a combination of maktos.jimmyseal.net/jip.html and anime in japanese with english subtitles. I want to be able to say that I intend to buy something. Before entering the shop. Is this the way (water is an example):
Mizu wa kau.
BTW: The hiragana I know are "a", "i", "u", "e", "o", "ka", "ki" and "ku".
Hardly enough to write sentences, hence the Romanji. How do you type japanese on these forums anyway?
