Okay, so I'm learning japanese by myself and sometimes I got confused of the extremely complex way to write some words. For example: 撃 = geki, so I can write it as (using katakana or hiragana syllabary) ゲキ. Is this correct? Now, my question is, does 'geki' mean something in japanese? So from here I understand that you can use kanji because besides of meaning an entire word, they can be used to write in japanese.
