However it seems as if you have changed the parameters of our discussion.
We where talking about the root origin of a specific word "Islam" and not the root origin of languages.
The Bible from what I see seems to lend support to the reference sources I listed instead of adding support to your views.
The word Islam is not found anywhere in the pages of it's 4000 year history.
The Hebrew word Salem is mentioned in four places I know of, Gen 14:18, Psa 76:2, Heb 7:1,2.in each case both Greek and Hebrew Strong's lists it as an early name for Jerusalem.
This is to be expected since the word Islam and the religion it stands for and the person [Mohamed]who created it was not born until seven centuries after the Old and New Testaments were written.
The Bible also states that God gave Jerusalem and quite a bit of the land around it,to Isaac, his heir Jacob [who like Abram renamed Abraham , was renamed Israel]and to Jacob's legal heirs.
Gen 35:10 And God said unto him, Thy name is Jacob: thy name shall not be called any more Jacob, but Israel shall be thy name: and he called his name Israel.
Gen 35:12 And the land which I gave Abraham and Isaac, to thee I will give it, and to thy seed after thee will I give the land.
Gen 13:15 For all the land which thou seest, to thee will I give it, and to thy seed for ever.
Gen 26:3 Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto thy seed, I will give all these countries, and I will perform the oath which I sware unto Abraham thy father;
This is much more than they have today including that which was renamed the West Bank which the Arabs are claiming is their's without any legal proof that I have seen.
Gen 15:18 In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates
The Arabs claim to be descendent's of Ishmael who according to the Bible is not a legal heir nor or his descendent's to the land he promised to Jacob and his heirs.
Heb 11:8 By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.
Heb 11:9 By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise:
If you check the legal records of heirs listed in Mat 1:1-17 and Luke 3:22-38 you will not find Ishmael listed as an heir to the throne of David[ a legal heir of Israel [Jacob] and the city in which it is said to reside in Jerusalem .
Mic 4:2 And many nations shall come, and say, Come, and let us go up to the mountain of the LORD, and to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for the law shall go forth of Zion, and the word of the LORD from Jerusalem.
Mic 4:3 And he shall judge among many people, and rebuke strong nations afar off; and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up a sword against nation, neither shall they learn war any more.
Sorry this is so long but I do not see how your reference source supports the idea that the Arabic word "Islam" is a "root of the word" Jerusalem and it's Hebrew root "Salem".
BTW though it may be hard for some to accept there are liberals, agnostics and even atheists who accept the fact that in certain areas the Bible as a historical document is quite accurate.
There are even some liberals who are Christians.
Hence, Hebrew "slm" and Arabic "slm" are remarkably similar, if not exact, derivatives of the same root word, and each language uses that root word in remarkably similar ways.
The Greeks and Romans upon adopting the Phoenician alphabet (which is based on a fundamental Semitic alphabet that serves Hebrew, Arabic, Aramaic and other Semitic languages) added vowels.
Did you ever notice that in English we have the word "peace" and the word "pacify". They come from the same root word in the Indo-European language group. There's a world of difference in them if you think about it.
I believe you are confounding what you believe to be the characteristic of Islam, the religion, with "Islam", the word.
