What does these non-numbered Monogatari novel's chapter title means? Based on Wikipedia, each English volume for the Monogatari novel book has its own chapter title, for example:


Chapter Zero
Chapter One
Chapter Two
Chapter Three
Chapter Four
Chapter Five
Chapter Six
Final Chapter 
Chapter Nixed
Chapter Snug
Chapter Idle
Chapter Change
Chapter Chaos


Basically, I roughly understand what does 'Chapter Zero' to 'Final Chapter' mean, I assume it is just for chronological meaning.

However, what does 'Chapter Nixed, Snug, Idle, Change, Chaos' mean? Any meaning behind why it is named after those 'term'?

Why don't they just name it 'Chapter Seven' and so on? And for Hanamonogatari, hana (花) means "flower", but why is its chapter named 'Chapter Change' instead of 'Chapter Flower'?
Obvious spoilers for Monogatari:

Chapter Nixed / Nekomonogatari Kuro
In Nekomonogatari Kuro, the inner, Black Hanekawa, wants to get rid of all of her problems such as her &quot;family.&quot; The word &quot;nix&quot; means &quot;dropping/getting rid of something&quot;, so you can make a connection there. However, my theory is this is the first time Hanekawa drops acting like she is an omnipotent being, especially the dialogue between Araragi and Hanekawa in the last episode. So I believe that is where this comes from.

Chapter Snug / Nekomonogatari Shiro
At the end of Nekomonogatari Shiro, Hanekawa finally was able to accept all of her problems and emotions thus resulting in inner peace for herself. The word &quot;snug&quot; means &quot;something comfortable or warm&quot;. She finally feels comfortable for being herself and doesn't think it's a bad thing thanks to Araragi. Also, let's not forget the talk between her and Araragi in the last episode. Probably she was feeling &quot;warm&quot; if you know what I mean. Also as a funny note, Tiger burns her so there is also this &quot;feeling warm&quot; meaning.

Chapter Idle / Kabukimonogatari
Well, this one is a bit ironic. In Kabukimonogatari, Araragi, again, wants to save someone. The lucky person is Hachikuji this time. Thus he and Shinobu travel to the past. That is so far from being idle, right? Anyway, they save Hachikuji from accident thus causing a time paradox where &quot;ghost Hachikuji&quot; never mentions where is Shinobu in Bakemonogatari since she is not dead in the new timeline. Thus in this new timeline, Black Hanekawa kills Araragi since Shinobu is not present at that time. She was &quot;idle&quot;.

Chapter Change / Hanamonogatari
Since this is one of my favourites, I will explain both the chapter and volume name. You see in Hanamonogatari, we are seeing the development of Kanbaru as a person while dealing with her past. She is finally dealing with her problems without the help of others ahem Araragi ahem. Well, he helps a bit, but not in a direct way. Anyway, my point is, we are witnessing her grown as a person like a blooming flower. So yea, that is the symbolism there. The word &quot;change&quot; also comes from there.

Chapter Chaos / Otorimonogatari
Well, I couldn't find a better word to describe this arc. Chaos. The problematic personality of Nadeko finally erupts thus causing the chaotic end result of the arc, namely, the death of our main cast. We are also seeing how Ougi really operates. Her whole aim to cause chaos in an enigmatic way for Araragi.



But why?

Nisio loves this type of puns and symbolism. Nearly every arc name contains one such as Hanamonogatari, Bakemonogatari, Nisemonogatari, etc. Others on the other hand directly give hints about the arc such as Owarimonogatari or Nekomonogatari.
