This article traces the intellectual roots and developments of the notion of competence in second language (L2) teaching and research. Since L2 teaching and research invariably concern competence of some sort (linguistic, communicative, interactional, or otherwise), there have been countless attempts to define competence from diverse theoretical…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

Today, scholars and students face an array of lingualisms: bilingualism, multilingualism, polylingualism, metrolingualism plurilingualism, codeswitching, codemeshing, and translanguaging, among others. Plurilingualism can be understood as the study of individuals' repertoires and agency in several languages, in different contexts, in which the…

Languages spoken in larger populations are relatively simple. A possible explanation for this is that languages with a greater number of speakers tend to also be those with higher proportions of non-native speakers, who may simplify language during learning. We assess this explanation for the negative correlation between population size and…

There is growing recognition that multilingualism is a norm rather than an exception and that it constitutes a default state of human linguistic competence. This phenomenon has become particularly relevant due to widespread, yet variously motivated, population movements as well as job-related mobility and the introduction of multiple foreign…

This article examines how, in a multilingual perspective, language competence is experienced, talked about and practiced by language users themselves. By viewing children as active co-creators of the spaces in which language is used, this article contributes to a research tradition in which focus is shifted from viewing the individual's language…
