To Publish
する verb
If 出版 is publishing, then the verb vocab version is to publish.
しゅっぱんする
The reading comes from 出版, so if you know that you know this. Also, it's just the kanji readings too, so no problemo for a person like you, I'm sure.
彼は有名な小説家だが、時々自費出版することもあるんだよ。
Although he is a famous fiction writer, he sometimes self-publishes his books.
