What does the word “Keltoi” means ?

Some time ago, I saw this on Facebook :

Let’s talk about the word “Keltoi” who produced the word Kelt or Celt nowadays.
The Greeks called them “”Keltoi”. The Germans called them “Kelten”. Who were the Kelts (Celts) ?
But what does “Keltoi” mean ? And what can we understand about our mysterious ancestors ?
In order to better understand this word, we must study the root of  “Kel”.
And it seems that two interpretations of the root “Kel” raise some questions… Unless they are complementary ?

Kel : a word linked to secrecy

This is the interpretation that we can read on the media of the oligarchy : Wikipedia

The official version admits that the interpretation of the word “Kel” is not certain. Kel could mean “hide”, “warm” or “force” see “the big ones”. It could have given (after many transformations) the verb “seal” (synonym: close, protect).
In this other post, the official version is supported : https://encyclopedia2.thefreedictionary.com/Keltoi

The post says, like Wikipedia, that the name was given by the Greeks (and undoubtedly then by the Germans) to these tribes. The post also gives a number of interesting details.
If we stop for a moment, we must try to understand who we were dealing with.
We are talking about a myriad of tribes who have a mythology closed of the Greek pagans, with a united political and religious system, although they spend their time having troubles between each other.
A moving people.
Who, officially, categorically refuses writing (because they had they worshipped the mystery ?). Except that regarding the writing, we know that this is incorrect, since the Kelt pagans had their own symbols : the oghams (similar to the runes of the Nordic pagans). Sacred and… secret letters.
We are therefore talking about an individualistic and extremely introverted people. We could even speak of “law of silence” or “omertà”. A people who firmly protected something. But what ? Knowledge? Women ? Treasures ? Probably all 3 since we know that they revered the sacred feminine. And they loved sorcery, jewelry, amulets, talismans, etc…
A druid told me he didn’t like the Kelts. For him they were invaders who had more to do with gypsies than anything else. I do indeed think that there is a link, especially when we see their passion for horses. I indeed think that we can speak of a rogue people (as the USA is a rogue nation), especially since from those ancient times, they spoke of freedom. And I think that their introversion has nothing to envy to the cowboys of Sergio Leone.
This other post explains the official version a little more: https://worldofcelts.com/post/182371241887/celtic-articles-keltoi-etymology
He adds in fact that secrecy was a characteristic of these tribes, which had greatly impressed the Greeks, in relation to their culture. Moreover, the author notes that the word “kilt” corresponds to a piece of fabric whose purpose is to “hide” a man’s genitals.
All these secrets correspond to a civilization more oriented towards the “black” color than the “green” color that the Irish show off. In my very opinion, the original Kelts were kind of some gypsy-gothic with a warrior-sorcerers mindset.

Moreover, when we look at the symbols of the Gothic culture, we often find the “triquetra”, the interlacings, and all the fantastic bestiary of the Kelts like the dragons. Moreover, “The Lord of the Rings” is described by observers as a Keltic, Gothic and even Christian work.

However, this post say that the main interpretations of the word « kel » can mean the « high », « noble » and « to strike ».
An elite warrior people ?

Kel : a word linked to vigor

Remember that the word “kill” looks like the word “kel”. That the act of killing can be violent, brutal etc… An act that could need to be hidden.
In this other post, from the same website, “kel” is interpreted more as a word linked to force : https://worldofcelts.com/post/164170427776/keltoi-etymology
We know that the word “Gal” which gave “Gaul” would have given “Gaillard” in modern French, which means “vigorous”.
“Bourbon” (the famous family of French kings) comes from “Borvo” (one of the names of the god of water) and means “boiling water”. And we know that the Kelts particularly revered water sources.
When we look at the Triskell symbol (whether it turns right or left) we can imagine that each ray is a hammer coming down. “Tris-kel” for “three shots” ? Possible, especially since the Kelts practiced triple death on some of their enemies (before hanging their heads on the saddle of the horses).
This striking Triskell can be found on the flag of the Isle of Mann, with these 3 feet adorned with sharpened spurs. We also find this Triskell on the flag… Of the island of Sicily (island birthplace of the word “mafia” as you know).
We find, strangely, a Triskell among the Japanese with the very aggressive symbol of the “Mitsu tomoe”. This symbol is found among the “clans” (a word from Scotland) of yakuzas… And in the Japanese culture, we find a symbol exactly similar to one of the Keltic crosses.
Finally, the symbol of the “Kolovrat” among Slavic pagans can be seen as a wheel made of scythes (instrument of death).
The goddess of winter among the Slavic pagans is called “Morana”. And the Keltic triple goddess of death, war and sex among the pagan Kelts is called “The Morrigan” (that some people called a “vampire goddess”).

Conclusion :

In my opinion, the first Kelts were some pure individualists. They were just caring about their businesses and to get the gods with them for that.
That’s it.
