adjective: Capable of being corrected.
From Latin corrigere (to correct). Ultimately from the Indo-European reg- (to move in a straight line, to lead or rule) that is also the source of regent, regime, direct, rectangle, erect, rectum, alert, source, and surge.
ka-ra-ya-juh-bhuul - Helping or promoting to sacrifice a mistake

ya - something that needs to be done, to make it a Potential Particle from verb, and many a times "i" is used to join words, and it can also become "ya".
juha - Sacrifice
bhuul - Mistake
There is no root for "ko-ra", except for some nouns, and the retrograde sound, "ku-ra" means "to utter a sound", and the prefix "ku" typically is used to indicate a "bad something" or to attach a negative meaning.
Anyway it shows corruptions of initiated sounds to un-initiated sounds, e.g. from someone knowing and taught in the science of sounds and thoughts, to someone using without the training. Similarly, the sound "bhuul" becomes "buhl", which backs what is said.
This points west-ward migration of the Indo Europeans, from North Western Indian Sub Continent, e.g. Sindu or Indus River area. This migration happened first in 40,000 BC and there seems to be many waves of "reverse settlements", as well as a major reversal from the North en side in 10500 BC, and this whole thing has added to the confusion in defining the source of Indo Aryans.
Everyone has a right to claim that they are the source of the Indo European, because like all children, everyone can say that. But it is the child who maintains strict adherence to the old ways of their parents, and shows minimal corruption to Sounds, Language, Religion, etc. can be used as a hint to where the Parent Civilization actually belonged to, by searching for the child who have maintained the closest connection to this Parent Sound, Language, Religion, etc.
This way, some villages in South India, which PBS show showed, still carry the pre-vedic sounds, before 40,000 BC, of their ancestors, but has close connection with Vedic Period.
The next thing that comes to us as in heritage is the Vedic sounds of the Vedas. For this reason, United Nations has called it the Cultural In heritage of the World.
