Colours, shapes, and textures

Prefixes used for specific colours, shapes, textures, and sounds. These are forms of sensory information that have a stronger psychocultural element to them than those in the category "Physical properties". For example, while there are wavelengths that correspond to certain colours, some colours (e.g. magenta) do not have associated wavelengths as they are created neuropsychologically. The sensory processes of colour vision, haptic information, etc is under Body Processes.

Shapes

Prefixes used to describe various geometric shapes. Primarily used for naming organisms.

• Boxy: Prefixes for shapes that are boxy - like a cube, square, prism, rectangle, rhombus, etc.
• Conical: Prefixes for shapes that are roughly conical, or bowl-shaped.
• Cross: Prefixes for shapes like a cross or X; linear with a cross-beam.
• Curly: Prefixes for shapes that are spirals, twisted, coiled, helical, etc.
• Filiform: Prefixes that are like a hair or string.
• Round: Prefixes for shapes that are like spheres, circles, disks, rings, etc.
• Spiky: Prefixes for shapes that star-like or otherwise spiky.
• Cylindrical: Prefixes for shapes that are cylindrical, tubular, rod-like, or phallic.
• Yonic: Prefixes for shapes that have an elliptic shape, but have tapering on the ends (e.g. fusiform), so are not properly Round.
• Branching: Prefixes for shapes that have a branching structure, like a feather or leaf.
• Bumpy: Prefixes for shapes that have rounded bumps rather than sharp spikes (see: Spiky).
