space-ineptitude
condition
The psychosomatic illness that causes the narrator's marooning. Manifests as becoming "an awkward burden" on the crew, unfit for continued travel. The condition improves with social belonging—"my old space-ineptitude sickness had left me"—and returns with exile: "I am so ill with awkwardness that I can no longer fly." The illness is fundamentally about connection, not space.
Cf. the teacher's maxim: "the only unforgivable sin in the universe is ineptitude."
communication sphere
technology
A "big metal ball" in which the narrator records his thoughts, functioning like a diary or ship's log. Can be swallowed when threatened ("I had barely time to swallow my communication sphere"). In extreme danger, it will be fired into the Galactic drift via the ejection mortar, hoping to be found by future travelers. The sphere is the story's frame device—everything we read is its contents.
ejection mortar
technology
Part of the "basic survival kit" provided to marooned crew members. Used to launch the communication sphere into orbit and the Galactic drift as a final testament. The narrator has "concealed" his mortar somewhere in the woods for this purpose.
Galactic drift
concept
The interstellar current or flow into which communication spheres are launched, hoping for eventual discovery by other travelers. The metaphor is oceanic—a bottle cast into cosmic currents. Implies a populated galaxy with established space travel routes.
cosmoscope
technology
A navigational device for taking bearings. The narrator has a "small cosmoscope" in his survival kit but shows no interest in using it—"I do not even recognize the system, though once this particular region was my specialty." His demoralization prevents even basic orientation.
change of blood
technology
Part of the survival kit. Implies the narrator's species can replace their blood supply, perhaps for adaptation to different atmospheres. He later manipulates his blood's "color and viscosity" to pass a human blood test for marriage.
universal language correlator
technology
An "abridged" version is included in the survival kit. Presumably aids in analyzing and learning alien languages. The narrator's rapid acquisition of English ("I was new at the language and its manner of speaking") may owe something to this device.
one thousand philosophic questions
technology
A "compendium" included in the survival kit "to exercise my mind." Implies a civilization that has catalogued unsolved philosophical problems—and considers intellectual exercise essential survival equipment. The questions are "yet unsolved," suggesting ongoing inquiry.
bug-kill
technology
A "small vial" in the survival kit, presumably insecticide or a defensive substance. Never used in the story. The mundane practicality of "bug-kill" contrasts with the philosophical apparatus.
giant grubs
taxonomy
The narrator's classification of humans. "Unfinished" creatures lacking a "complete outer covering," living "under rocks and in masses of rotten wood." The grub metaphor emphasizes humans as developmentally incomplete—larval beings who should have metamorphosed but never did. "Nothing in nature gives the impression of so lacking an outer covering as the grub, that obese, unfinished worm."
cocoon
taxonomy
Clothing, defamiliarized. "A loose artificial sheath covering the central portion of the corpus." Humans "seem unable to divest themselves of it, though it is definitely not a part of the body." The narrator theorizes "some psychological bond that dooms them in their apparent adult state to carry their cocoons with them"—arrested development made literal.
flesh stilts
taxonomy
Human legs, defamiliarized. Precarious supports for upside-down travel: "I would not stagger along precariously on a pair of flesh stilts with my head in the air, as you do."
gravity-bound
concept
A fundamental limitation the narrator observes in Earth creatures and human cognition. Cattle don't fly over obstacles; human language has "thoughts . . . chained to its words. There seemed nothing in them above the vocal." The opposite of the narrator's telepathic, flight-capable species. A gravity-bound mind cannot transcend its immediate situation.
Beta and Gamma types
taxonomy
The narrator's classification of human sexes as polarities in a "simultaneous polarity equation." "Boy and Girl types" whose "interlocking attraction-repulsion complex" drives behavior. There is "a sort of poetic penumbra about the whole thing that tends to disguise its basic simplicity." He discovers he is Beta-type when attracted to Gamma-type Margaret.
first aspect numbers
concept
The basic numerical system used in Earth gambling, which the narrator finds primitively inadequate. "First aspect numbers do not carry within them their own prediction." His species has access to "second aspect series" mathematics that includes prediction—making all gambling trivially solvable. Humans wager "blindly, not knowing for sure whether they would win or lose."
second aspect series
concept
Higher mathematics possessed by the narrator's species, including a "prediction key" that lies "over the very threshold" of first aspect numbers. Makes gambling outcomes predictable. Humans lack even the awareness that such mathematics exists.
pseudodendrons
taxonomy
Trees, defamiliarized as imperfect versions of their home-world equivalents. "Enough like trees to remind me of trees." Part of the narrator's taxonomy of Earth as similar-but-inferior to home. The prefix "pseudo-" marks everything on Earth as a degraded copy.
myopic quadrupeds
taxonomy
Cattle, defamiliarized. "Hump-backed browsers" who "pay me scant notice" and spend "nearly their entire time at feeding." They are "as gravity-bound as a newborn baby." Their "vibrant windy roar" yields no meaningful communication. The narrator may be invisible to them.
blob
taxonomy
Human epithet for the narrator, used throughout the story. Legally enshrined in the ruling that "a blob is not a person." The narrator protests—"I am not a blob. I am a creature superior to your own kind"—but cannot escape the category. The word reduces him to formless matter, denying his personhood and his form.
Florida
place
The "planet" where the narrator is marooned. He initially thinks it might be the world's name: "Is the name of this world Florida?" Eustace corrects him that it's a state—"the greatest state in the universe." A "green, somewhat waterlogged land of pleasant temperature" that allows him to dispense with "much bothersome equipment."
Planet Hecube
place
A planet where "full summer turns into the dead of winter in minutes, to the destruction of many travelers." Invoked as an analogy for the narrator's sudden fall from prosperity. The classical echo (Hecuba, queen of Troy who lost everything) is likely intentional.
whing-ding
concept
A party or celebration. The narrator promises to "throw a whing-ding . . . as soon as I find out what a whing-ding is." His willingness to adopt human customs without understanding them reflects his desperate desire to belong—and his fundamental alienation from what he adopts.
environmental control
concept
The narrator's stated goal: "It was necessary that I establish control over my environment." Wealth provides this control temporarily. But his environment is human society, which operates by rules he cannot ultimately overcome. Legal personhood is not purchasable.
