In this paper, a characterization of the language varieties and congruence varieties corresponding to M -solid pseudovarieties is presented. Taking into account the isomorphisms of the Eilenberg-type correspondences, each complete sublattice of pseudovarieties corresponds to a complete sublattice of language varieties, as well as another one of congruence varieties. For the varieties of tree la...

Taking into account the isomorphisms of the Eilenberg-type correspondences, each complete sublattice of pseudovarieties corresponds to a complete sublattice of language varieties, as well as another one of congruence varieties.

Despite the global spread of English, it seems that voices from Persian-speaking teachers concerning English as an international language (EIL) teaching methods and materials are underrepresented. The present study set out to explore how nonnative Persian-speaking English language teachers respond to the increasing global dominance of EIL and native- and non-native-speakers’ language norms with...

This paper presents VarClass, an open-source tool for language identification available both to be downloaded as well as through a graphical user-friendly interface. The main difference of VarClass in comparison to other state-of-the-art language identification tools is its focus on language varieties. General purpose language identification tools do not take language varieties into account and...
