We use two coupled equations to analyze the space-time dynamics of two interacting languages.Firstly, we introduce a cohabitation model, which is more appropriate for human populations than classical (non-cohabitation) models. Secondly, using numerical simulations we …nd the front speed of a new language spreading into a region where another language was previously used. Thirdly, for a special case we derive an analytical formula that makes it possible to check the validity of our numerical simulations. Finally, as an example, we …nd that the observed front speed for the spread of the English language into Wales in the period 1961-1981 is consistent with the model predictions. We also …nd that the e¤ects of linguistic parameters are much more important than those of parameters related to population dispersal and reproduction. If the initial population densities of both languages are similar, they have no e¤ect on the front speed. We outline the potential of the new model to analyze relationships between language replacement and genetic replacement.

“…The three states are: the fraction of speakers of language A (denoted by p A ), the fraction of speakers of language B (denoted by p B ) and the relative status of language B (denoted by S). The fraction of bilingual speakers is simply given by p C = 1 − p A − p B , and the relative status of the majority language A is given by 1 − S. In Fernando et al (2010) the authors criticize such an assumption in the model of Minett and Wang because it implies ''that it is impossible to make one language more attractive without making the other less so'' (Minett and Wang, 2008, p. 50). However, in a language competition situation, where individuals have to decide for one language, the other or both, this assumption makes sense when we think of relative attractiveness instead of absolute attractiveness.…”

h i g h l i g h t s• A dynamic control model for the competition between two languages is developed.• Family formation and intergenerational language transmission are modeled explicitly.• Investments into status planning can be used to support the minority language.• If bilingualism is valued high enough, survival of both languages can be optimal.• Optimal steady states depend on initial distribution of speakers. a b s t r a c tWe develop a dynamic language competition model with dynamic state intervention. Parents choose the language(s) to raise their children based on the communicational value of each language as well as on their emotional attachment to the languages at hand. Languages are thus conceptualized as tools for communication as well as carriers of cultural identity. The model includes a high and a low status language, and children can be brought up as monolinguals or bilinguals. Through investment into language policies, the status of the minority language can be increased. The aim of the intervention is to preserve the minority language in a bilingual subpopulation at low costs. We investigate the dynamic structure of the optimally controlled system as well as the optimal policy, identify stable equilibria and provide numerical case studies.

“…This model [5] of the mechanisms of language extinction and revitalization strategies to save endangered languages is a mechanistic model characterized by parameters that can be measured. Also, bilingualism has been incorporated into the model, so as to mainly focus on the functions of the child's family type and speaker frequency rather than describing the child's language type, monolingual or bilingual.…”

A New Probabilistic Model of Language Competition, Endangerment and Extinction

Language endangerment is a growing concern in the world today. The speakers of the less dominant language in the society tends to get more inclined towards the more dominant language because of many reasons. Due to this, the speakers of the less dominant language decreases, eventually leading to the extinction of that languages. In this paper, a probabilistic mathematical model has been proposed to check language shift for the intergenerational language transmission between parents and their offspring based on some factors that has been taken. A Markov chain model is also defined to show the change in language transmission for grandparent and grandchild.
