A few very important ones are described below. Others are implemented in the Gellish Communicator software reference application that is available on GitHub. |
| - | **Rule 1: Facts shall be expressed as binary relations between things** | + | **Rule 1: Ideas shall be expressed as binary relations between things** |
| - | Facts shall be expressed in Gellish English by one or more binary relations, each of which shall relate two things on a single line in a Gellish Database table. A related thing may be anything, including an individual thing or a kind of thing, a single thing or a plural thing (collection) and may be real or imaginary. Only in the case of synonyms and translations the related things (referenced by their unique identifiers) shall be the same while their names may be different. | + | Ideas, such as assertions, queries, etc. shall be expressed in Gellish as one or more binary relations, each of which shall relate two things on a single line in a Gellish expression format table. A related thing may be anything, including an individual thing or a kind of thing, a single thing or a plural thing (collection) and may be real or imaginary. Only in the case of synonyms and translations the related things (referenced by their unique identifiers) shall be the same while their names may be different. |

It is a concept that is already defined in the [[:Gellish English Dictionary|Gellish Dictionary]] and is selected from that dictionary (its name or synonym and unique identifier). \\ |
| - | 2. It is a new concept (kind of thing) that is propertly defined occording to the Gellish [Proper definition of a concept|rules for proper definitions of concepts]]. This includes that the new concept is defined by the specification of an explicit specialisation relation that defines it as a (proprietary) subtype of one of the concepts that already exist in the Gellish English Dictionary. | + | 2.
