ATH- Holy Qur’an, Thinking Abstractly and Language

How did Allah preserve “The Original Arabic Language”?  According to the history of the Arabic language -

“The word “Arab” [`arab] means “nomad”[1], and Arabic was originally the language of itinerant tribes in the desert regions of the Arabian Peninsula.  The very inaccessibility of much of that terrain (including what is now known as “the Empty Quarter”) may well account for the fact that, of all the Semitic languages, Arabic seems to be the one that has preserved many of the features of the …. so-called “Proto-Semitic” from which the family of Semitic languages was to emerge over time in its different forms.”[2]

[1] Saracen is/was a Middle Ages term for Arab that means “nomad”, as well.
