I put your question into ChatGPT to see what it would come up with, I think there are some good potentials in here:

The concept of inorganic species naming themselves involves a blend of creative linguistics and speculative fiction. The term "mechanoid" is indeed a common and somewhat generic term in science fiction to refer to robotic or mechanical beings. If we consider that an inorganic species might develop its own sense of identity and culture, they could potentially adopt a name that reflects their unique characteristics and philosophical perceptions. Here are some inventive alternatives to "mechanoid" and the thought processes that might lead an inorganic species to choose them:

1. Synthetix

Derived from "synthetic," indicating their man-made origins, combined with a twist that makes it unique and culturally specific to them. It emphasizes their artificial nature but also sounds like a name they might proudly identify with, suggesting sophistication and complexity.

2. Auracite

Combining "aura" (a term sometimes used to describe a manifest energy or presence) with "cite" (from citadel, suggesting structure), this term could denote inorganic beings who perceive themselves as both energetic and structured, emphasizing a complex framework that supports what might metaphorically be described as their soul or spirit.

3. Ferrumin

Rooted in "ferrum," the Latin word for iron, a common metal. This name could be embraced by metallic beings, emphasizing their strong, enduring nature. It connotes a sense of agelessness and durability, key traits for inorganic forms.

4. Electon

Derived from "electron," highlighting their reliance on electrical energy, this name would fit a species that views itself as inherently tied to electric or energetic phenomena. It emphasizes their dynamic and energetic essence.

5. Crystalline

For a species with a crystal-like structure, emphasizing transparency, precision, and symmetry. This name reflects physical beauty and an orderly, geometric nature, which could be central to their identity.

6. Golemics

Inspired by "golem," a mythical being animated from inanimate matter, combined with a suffix that suggests a scientific or systematic study, like "physics." This could be suitable for a species that sees itself as crafted with purpose and potential beyond mere machinery.

7. Quantix

Influenced by "quantum," reflecting a fundamental connection to physics at a microscopic scale. This could be particularly apt for a species that perceives themselves as operating on or exploiting quantum mechanical principles.

8. Silicoid

Rooted in "silicon," which is often used in electronic components and could be a base element for these beings. It emphasizes their elemental nature and could be seen as defining their "species" from a chemical standpoint.

9. Kinetix

From "kinetic," emphasizing motion and energy, this name would suit an inorganic species that values mobility and the flow of energy through their systems as central aspects of their being.

10. Neuracite

Combining "neural" (nerve, relating to the nervous system) with "cite" (implying a place or community). This could be used for a species that has developed a form of artificial intelligence or neural networks akin to a brain, emphasizing their intellectual and cognitive capacities.

Each of these names carries connotations that reflect how the species might view themselves in terms of composition, capabilities, and philosophies. In your writing, picking a name that aligns well with the species’ characteristics and the themes of your narrative can enrich world-building and add depth to the portrayal of these beings.
