We think of Numeronomy as idea set theory, the interdisciplinary study of idea sets across cultures, related to computational lexicology and Bennettian Systematics.

We use Polynym to describe idea sets (as part, step or type), such as:

Freud's three parts of the psyche:

{P3:psyche|part|Freud} =
  { id, ego, superego }

The Five Stages of Grief:

{P5:grief|step} =
  { denial, anger, bargaining, depression, acceptance }

The Seven Deadly Sins:

{P7:deadly sin|type} =
  { wrath, greed, sloth, pride, lust, envy, gluttony }

The union of Polynyms results in a set of combined elements we call a Unionym:

{P2:yinyang} ⋃ {P3:psyche|Freud} =
  { ego, id, superego, yin, yang }

We call the set at the intersection of two Polynyms (their shared elements) a Sectionym:

{P4:self|Jung} ⋂ {P7:energy|chakras} = { feeling, thinking }

Supernym/Subnym represent superset/subset relationships between Polynyms:

{ feeling, thinking } ⊆ {P4:self|Jung} ← Subnym ⊆ Supernym
{P12:star sign} ⊇ {P4:fixed star sign} ← Supernym ⊇ Subnym

We call the relationships between elements of two Polynyms a Polymap.

Relationship types are adopted from ConceptNet:
