Moreover, amongst the few borrowed words, there are a sizable number of what are called "reversals". In other words, when IndoEuropean, Semitic, and other peoples met in the Mediterranean basin, since some of them wrote from right to left and others wrote from left to right and since vowel sounds were not written at first, when one nation borrowed a word from another, the order of consonents frequently got reversed.In a word, "no." If that's not enough words, "No, no, no, no, no, no, no, no, no!"
In times before literacy was common, when people borrowed words as a result of foreign contact, they borrowed the sounds, not the written forms. It's absurd that anyone would get the sound wrong because the writing is "backwards." In the times you describe, the typical person couldn't read or write his own spoken language, much less any other. Script differences would not cause the confusion you attribute to them.
Forget about reversals. Of the anomalies I note on the page in question, the biggest is really the non-relationship between the IndoEuropean and Semitic language families. The two groups are racially the same and could not have split up more than a few thousand years ago and the languages should be strongly related given anything like standard theories.
In fact, The divide between English and Russian is three or four thousand years back and you can still recognize a lot of Russian words as basic kinds of IE roots.
Plamiya and flame are the same word, ogon and ignite (agni/fire) are the same word, loeffel/lozhke/ladle (spoon) the same word, p/f words, fall/pal etc., pronouns are nearly the same, basic numbers nearly the same, family members the same, words for things like milk, wine, water the same, simple conceptions like work (arbeit/rabota/labor) the same (other than for the reversed consonents...)
By all rights that kind of stuff ought to be there going from IE to semitic languages as well, but it ain't...
