The concept may be defined as relating directly to the health/vitality /wellbeing (i.e. sustainability) of these languages. In the paper, an attempt is made to further define the concept in terms of a set of parameters as well as to show that natural languages differ as to the degree of their overall robustness.enArtykuł
