Introduction: The Shape of Oid
Imagine the word "humanoid"—a figure resembling a human yet distinct in its otherworldliness. The suffix "oid," pronounced as "oyd," captures this essence of resemblance. Derived from the Greek word eidos, meaning "form" or "shape," it has become a linguistic staple in describing objects, organisms, and concepts that bear likeness to something else. Its applications span geometry, biology, and even science fiction, making it a fascinating root to explore.

By the 17th century, "oid" entered scientific terminology to describe objects that resemble specific shapes or forms. Over time, it gained prominence in fields like biology, astronomy, and geometry, helping to classify and articulate the likeness of forms and structures.
