Hebrew and in fact all Semitic languages have three consonant roots written down and "inflicted" to make verbs and nouns.
I'll give an example in English so you get the idea
Robin sang music asHe floated onThe river water.
RBN SNG MSC asH FLTd onT RVR WTR
These are the three letter "roots"
of the words.
Robin - R.B.N
Sang - S.N.G
Music - M.S.C
Float - F.L.T
River - R.V.R
Water - W.T.R
In Hebrew it is easy to see how a word originated from a natural sound that has to do with it. Many words clearly follow that pattern. There are many words like that in English ("chirp" for example) but it is usually harder to trace them to the origin, because of the vast changes most words went through.
In Hebrew, (and Arabic and Aramaic) most of the words fit this pattern of three root letters, except those that don't.
My claim is that its easier to reconstruct an ancient system that had a single "barking" short word used as a command with only an opening set of consonants, a single closing set of consonants and one single vowel, if any.
This would explain many and in fact most of the inflictions that lose the extra vowel. Instead of Adding another root letter to a vowel, just attach the extra consonant to the beginning or end of the word.
In our English example:
S.N.G from sang does not have two vowels. It is not Senag, it is S a Ng (sang) a single vowel moving the S and ending with the single Ng sound.
F.L.T from float does not have two vowels. It is not FeLot, it is FL o T (float).
It is not WeRyT it is WR y T. In effect sounding like RyT. (write). Two consonants and one vowel.
Semitic languages are: : Ancient Akkadian, Babelonian, Assyrian, Neo-Babilonian, Ancient Egyptian, Ethiopian Amharic, Gez, Coptic, Tigrenia, Canaanite from Be'eroth, Gshur, Sydonite, Ukarit, Moavite, (Yemenite, Polish, Galitzianer and Sepharadic modern) Hebrew and the many dialects of Arabic including Maltese and parts of Farsi, Urdu, Turkic, and Swahili.
In Hebrew:
K.T.B - for writing.
KaTaB - wrote (he)
KaT B a - wrote (she)
KaTaB nu - wrote (we)
yiKToB - (will) write (he)
tiKToB - (will) write (she)
etc.
Similar to the English verb
write! (anyone single or plural male or female, order to do in the future)
writing! (anyone, ongoing)
wrote. (anyone, in the past)
My claim is that the Hebrew (and semitic) words all originate from a short utterance that made a sound, originally a simple command with a single syllable.
The are only two parts to a no-vowel - closed sylable: The opening consonant(s) and the closing consonant.
For Write, writing, wrote, written (and even the word "word") there are two ROOT SOUNDS: WR and DT.
Everything else is just a variation on that.
In Hebrew its KT and B.
The Biblical Hebrew way of giving an order to write something down was short: KToB.
And THAT is the root: Two sounds: KT, B.
My claim is that the theory of a three-letter root for every Hebrew word has many cases where it just doesn't exactly apply, and a "hidden letter" which "fell" at some stage must be reinserted into the words.
So HaLaKh means went (with the root set at H.L.K) but YeLeKh means go (with no H root letter at the beginning), whereas actually, IMHO the root should be only the "barked" command Lekh! Go!! and thus should be: L.K.
Same goes for YaShaV sat down (root: YSV) but neSheV we will sit missing the Y only leaving S.V. (ne - is short for "we") . So it should be SheV! Like the command, meaning: Sit!
My claim is that ALL words are not words with three-consonant roots but actually two-consonant words, with either the opening (the onset) or the closing (the coda) of the syllable being a double consonant or even more. Some times the extra sound is heard, other times not. Some times they are nasal or vowel additions.
in the English word Float from Flow - has the onset (opening of the syllable is FL then the vowel o, and finaly a WT sound. So FL o WT.
The word NaHar - snored, just like in English has only two basic sounds: Sn and R. In Hebrew its NHh and R which is the throaty Hhet sound with a bit of nasality: NHhaR.which comes from the HhhhhhRrrrrrr sounds of snoring.
Same goes with Tsipor a bird and Tsafar - honked, and Aramaic Tsafra - morning (because of the birds singing): These like the English word Chirp (TShiRP with TSh and Rp - from the chirping sounds) in Hebrew should have only two consonants: TS is the first one, and PR is the second one.
The rest of this idea is just details and answering questions.
