Misconception 1: Any shared attribute is a genus.
Correction: A genus expresses an essential element common to distinct species, not merely an accidental similarity such as colour.
Misconception 2: A word must always be either genus or species.
Correction: Animal is genus relative to human and horse, yet relative species under growing body.
Misconception 3: Every real species must also be relative species.
Correction: The commentary uses point as real-only and animal as relative-only to demonstrate partial overlap.
