Isaac Asimov: Many of his stories use Idiosyncratic Episode Naming of short titles, explained by Asimov as the result of a particularly poorly-written (and titled) story from his youth.* "The Weapon Too Dreadful to Use" He claimed in a later introduction to the story that its flaws and inaccurate title permanently soured him to longer titles.
Emma: It's a Protagonist Title, as the novel is called after its heroine, Miss Emma Woodhouse.
Persuasion: The novel's protagonist was persuaded by her godmother not to marry her one true love. Forms of the word "persuade" appear a lot in the text, and forms of persuasion shape the development of the story. The novel was named after Jane Austen's death by her heirs (the manuscript was titled The Elliots).
Sanditon is an unfinished novel. It's also The Place: Sanditon is a seaside town where the story takes place.
Several works in the Vorkosigan Saga (internal chronological order; Barrayar, Cetaganda, and Komarr are also examples of The Place, being fictional planets in the "Vorkosiverse"):
Barrayar
Cetaganda
"Labyrinth" (a novella)
Memory
Komarr
Cryoburn
All of the individual novels in The Sharing Knife series (internal chronological order):
Erin Hunter: This is the Idiosyncratic Episode Naming of this, which is also an occupation, for her series'. However, most are commonly known by their title plus the species the work is themed around (including on this Wiki) for convenience's sake:
Chrysalis (Beaver Fur). It may be referring to the Terran's spaceship body, which is described as a smooth, elongated shape, and more metaphorically, it may refer to the body's role as the Terran's shell, or its nature as the source of the transition from a biological humanity to an android one.
The Empirium Trilogy: The titles of each novel are singular words comprised out of two. The first is Furyborn, the second Kingsbane, and the third Lightbringer.
Flawed and the sequel, Perfect, both about the in-universe flaw system in the story and how the protagonist, who was seen as perfect, ended up being flawed.
The Golem, by Gustav Meyrink: Not only is each chapter titled with just one word, they are all just one syllable long (in the original German). Some examples:
"I"
"Prag"
"Schlaf"
"Tag"
Gone, where everyone above 15 suddenly disappears. The sequels also count:
Hunger, which deals with the food getting scarce.
Lies, where several charcaters lie to each other which leads to disaster.
Plague, where a deadly disease starts spreading.
Fear, which deals with the dome going black and all light disappearing, causing a lot of fear.
Light, where the literal light comes back and where the characters are finally having hope again.
The Orthogonal trilogy, though the individual book titles have many words. Orthogonal is a referent to orthogonal matter, which plays a large part of the story's physics.
Singularity: The book is presumably named for the black hole-ish nature of the Playhouse, and a singularity is the supermassive center of a black hole.
Wagons West Of the 24 books of the original series, only New Mexico! had more than one word. The follow up series had only two one-word titles, and they were the last two books.
