Is the Egyptian word NTR(god) from Nut/Neith + Ra?

Schwaller de Lubicz explains in Le Temple de l'Homme (Caracteres, 1957) that in the ancient temple civilization of Egypt, numbers, our most ancient form of symbol, did not simply designate quantities but instead were considered to be concrete definitions of energetic formative principles of nature. The Egyptians called these energetic principles Neters, a word which is conventionally rendered as "gods." To conform with the true meaning of the symbol in ancient Egypt, we ought to use the Egyptian term Medu-Neteru, the Greek translation of which, "heiroglyphs," distorts the Egyptian meaning. Medu-Neteru are the Neters, or the principles conveyed by a sign.

"'Divine" man (without this part of the brain ) represents the Principle or Neter, capable of living and acting, but only as the executant of an impulse that he receives; hence, he plays the role of an intermediary between the abstract impulse, outside of Nature, and its execution in Nature, without actual choice. In this regard, this entity has a primitive, and "prenatural" character

...each of these individual members of the vegetable kingdom belongs to a genus, and this genus to a family; and these families belong to an original "lineage." At the head of this lineage is a Neter, a "Principle" synthesizing all the characteristics of this lineage: its number, its rhythm, its classification in the general harmony. Let us further elucidate, by means of a geometrical image, the role of the Neter as head or Principle of a lineage.

First translated by early Egyptologists after Champollion as God or Goddess, this meaning ["god"] has since been challenged. R A Schwaller de Lubicz was one of the first to question this translation in the early 1950's, choosing rather to define Neter as principle" and/or "attribute", as a divine aspect of the whole, not in the sense we use the word Deity. The [ Latins] derived their word Nature from Neter, therefore equating the Divine with the natural as the Khemitians taught them. The ancient Khemitians knew every principle or attribute of Nature was also divine, of God - all interconnected and interrelated to the whole, the source.

...there are basic principles concerning the order of nature that continue through these transformations, such as the identification of cosmic elements with real divinities possessing a personal existence. Most important of these principles for the understanding of the order of nature is the Neter , which has received many interpretations, some even equating it with the Hebrew Wl. The Neter is a principle conveyed by a sign, the hieroglyph being itself called Medu-Neteru. It is the Idea of which a material object is the crystallization.

The order of nature is the reflection of the order that belongs to the realm of the principles or Neteru, which man also carries within his being as a consequence of his central position in the cosmic order. 'Every natural type is a revelation of one of the natures and abstract functions that rule the world, a verb of the divine language —that is, the entities or fully realized Principles (Neteru).
