Body processes

Category description: The dynamics of bodies: e.g. sleep, pregnancy, olfaction. Sensory information (e.g. colour, temperature) are categorized under "Colours, shapes and textures" and "Physical properties". Entries here must be applicable to species other than humans. Bodily processes that are human-specific go under "Human acitvities". Subcategories:

  1. Bodily needs and functions: Basic physiological needs and functions, such as sleep and eating.
  2. Cellular processes: Cellular processes, such as mitosis and meiosis.
  3. Emotion: Affective states brought on by neurophysiological changes in the body.
  4. Pathological: Terms that involve pathologies (e.g. emeto for vomit, emesis).
  5. Reproduction: Prefixes concerning reproduction in a physiological sense; human sexual behaviour (e.g. sado-) is under Human Activities.
  6. Sensory: Prefixes concerning the neurophysiological element of sensory perception. Sensory information such as specific colours are under "Colours, shapes and textures" and "Physical properties".
Prefixes categorized as Body processes.

Colours, shapes, and textures

Category description: 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. Subcategories:

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