This article analyzes the phenomenon of orthographic destabilization in the Russian language in the early XXI century. The phonic and graphic word forms compete in the process of phonetic-graphic adaptation of global lexis to the conditions of the accepting language. The spring to life of the loanword in the new orthographic conditions is associated with variability of the form. Over time, the form of the word stabilizes, resulting in formal de-barbarization of the loanword. In the early XXI century, certain lexical globalisms retain variability even after codification in the normative and specialized dictionaries. The concept of overcoming the variability of orthographic norm in the conditions of linguistic globalization is not being fully implemented, causing orthographic destabilization. On the one hand, the rollback to orthographic variability demonstrates complex vicissitudes of the formation of speech culture of the era of linguistic globalization, while on the other hand is substantiated by specificity of the mechanisms of phonetic-graphic adaptation of loanwords in the Russian language. The variability expands due to the adaptation of new words from the global English departs from the existing orthographic rules. The author demonstrates the phenomenon of orthographic destabilization using the representative examples; as well as concludes that it is of destructive nature, and should be overcome by hewing to the relevant orthographic trends and rules.
