Listening to Japanese music I stumbled upon this song called 僕たちの失敗 by 森田童子. I liked it so I went to look up for the lyrics and its meaning, and there is a part of those in which something is used that I would like to have explained.
The thing is, at some points in these lyrics katakana is used at the end of okurigana. What's the meaning? What's the usage? Why are those sentences written like that?
