Does the Hebrew word "Torah" originate from BOTH the words “Hora’ah” (meaning, Teaching) and “Orah” (meaning, Light)?
The accurate meaning of “Torah” is twofold. Firstly it comes from the word “hora’ah,” which means teaching .... The second ... is from the word “orah,” which means light.
This is the teaching from a rabbi https://www.aish.com/atr/What-is-Torah.html
But this rabbi does not reference his "answer from a reputable source", which is what I am looking for; that is, any source that is accepted here at miyodeya.
Here at miyodeya, there are a number of questions in regards to the meaning of the word "Torah"; such similar questions were not noted as duplicates, because of the various angles, in which it was asked; my hereby question is seeking an authoritative answer about the derivation of the Word "Torah" from BOTH “Hora’ah” (meaning, Teaching) and “Orah” (meaning, Light).
