The eymology of Norwegian language word Gruig

To find the evidence that the Albanian language once was the first and the only language spoken in Europe and the closest language to PIE is not so difficult. The linguists lack the desire and ability to find the evidence of the old Albanian language.

There is a word *Griug in the Norwegian language.

Griug means to wake up early.
The word is known in several different dialects and is used for a person who is fresh in the morning, has just woken up from sleep and has not spent his energy
In the Hellbillies hit, Mørkemann translates to the dark man (from Albanian Murrët(dark) Man, or Muzg (dark) man is the opposite of what Griug understands - to rise at dawn. 

The word griug can be accurately assumed to be a derivation of the verb "to rise at dawn." If you are griug, you are up, awake when the day dawns, the morning light. In Norwegian we also have another word grýjandi, which is mistakenly translated as gray light - the transition between black night and sunrise, it is the opposite that gray as a color comes from the color of the sky at dawn.

This is how Norwegians identify the word griug.
To find  the etymology of this word does not require many schools and diplomas.
The following words of the Albanian language that are all connected with with this word and all of them have the concept G are:

GRIUG comes from the Albanian verb NGRE.
The etymology of NGRE and its meaning in Albanian.
ngre
Alternative forms
ngredh
ngreh
There are some variations of the word that cannot be found in the Albanian dictionary.
The Arvanites of Greece and the Cham dialect say "griu - grehet instead of *ngre without *N. In Geg Albanian the form is *gre, like in the sentence "ai a gre herët" which means he wakes up early. The north-east Albania such as Mat, Mirdite, Dibra e Madhe, Peshkopi and elsewhere they use the form "gre" and not the standart form *ngre:

Etymology 

The linguists think that *ngre comes from Proto-Albanian *̊kre(i/h)-, from Proto-Indo-European *ḱerh1-, *ḱreh1- (“to grow (up)”)

And, I think the meaning "to grow" of *gre is not accurate. 

It is more complicated then "to grow".

The performaces meanings of *gre is "to grow" plus:

-lead from the bottom up;  to take it from where it is and to put it somewhere higher. Picks something off the ground or floor and holds it suspended in the hands, wake him up; gett him out of bed (from sleep), get up early.

Meanings:
to raise, to elevate, to lift
to erect
to wake 
(colloquial) to arouse (to cause to have an erection)
