- Ideal logical language(the proposed system for expressing metaphysical concepts)
- A perfectly precise artificial language designed to represent reality and truth without the confusing ambiguities of everyday language.
- Non-paronymous(describing a type of word that does NOT signify metaphysical concepts)
- Words that don't share a common root or aren't related by variation in form.
- Particles(as used in physics and philosophy of science)
- The tiniest bits of matter that make up everything in the universe, like electrons or photons.
- being(Aristotle's rejection of being as a genus)
- The class that contains all and only things that exist; proposed candidate for a highest kind.
- essence(Medieval realist metaphysics)
- The defining nature of a species, held by some to be distinct from and capable of surviving the destruction of all individual members of that species
- metaphysical concepts(metaphysics)
- Big, abstract ideas about what reality fundamentally is—like existence, time, causation, or what it means to be something.
- paronymous(Logical grammar; mismatch between grammatical and logical form)
- A word whose grammatical form is derived from another word (in this case, 'mawjūd' is derived from the verb 'wajada'), such that the derived form carries morphological traces that do not correspond to its intended logical function
- unity(Derived from being by adding the notion of indivision alone.)
- Being that is undivided; the concept of being with the purely negative addition of indivision.
