Religious regimentation?

I was brought up on familiar terms such as khuda hafiz, shabe -e- barat,, etc. but the current official format is to use the Arabic versions. Is the use of language in local religious, social practices being subtly controlled? Why? There are hundreds of languages in all communities all over the world, and establishing communication with the beloved (divine or human) is a very intimate and personal process.

Watch the relationship between a new-born baby or child and the mother. No training, orientation, preconditions or formalities, and the natural interaction is independent of human language. It is spontaneous and intuitive. What is wrong with this scenario?

The long-term implications of such fads and orientation have to be explained to the masses to avoid misunderstanding in matters appealing to the heart, rather than to the head (belief and logic). As an educated pensioner, I am confused, and would like to be enlightened.
