Explaining the diversity of languages across the world is one of the central aims of typological, historical, and evolutionary linguistics. We consider the effect of language contact-the number of non-native speakers a language has-on the way languages change and evolve. By analysing hundreds of languages within and across language families, regions, and text types, we show that languages with greater levels of contact typically employ fewer word forms to encode the same information content (a… 
Language structure is influenced by the number of speakers but seemingly not by the proportion of non-native speakers
The results suggest that there is indeed a relationship between the number of speakers and (especially) information-theoretic complexity, i.e. entropy rates, and that this relationship reflects a negative selection against morphological paradigms that are hard to learn for adults.
The Entropy of Words - Learnability and Expressivity across More than 1000 Languages
The choice associated with words is a fundamental property of natural languages. It lies at the heart of quantitative linguistics, computational linguistics and language sciences more generally.
A model of contact-induced language change: Testing the role of second language speakers in the evolution of Mozambican Portuguese
It is suggested that multiple introductions of a new linguistic variant by different individuals may be the mechanism by which language contact accelerates language change.
Overview: Debating the effect of environment on language
If languages do indeed evolve then they must show the three crucial aspects of an evolving system: variation of traits, inheritance of those traits, and the differential survival—that is selection—of
A Comparison Between Morphological Complexity Measures: Typological Data vs. Language Corpora
This paper uses human expert judgements from the World Atlas of Language Structures (WALS) to compare them to four quantitative measures automatically calculated from language corpora, and finds strong correlations between all the measures.
Imperfect language learning reduces morphological overspecification: Experimental evidence
It is often claimed that languages with more non-native speakers tend to become morphologically simpler, presumably because non-native speakers learn the language imperfectly. A growing number of
Variation in Word Frequency Distributions: Definitions, Measures and Implications for a Corpus-Based Language Typology
It is argued that quantitative measures like the NFD can advance language typology beyond abstract, theory-driven expert judgments, towards more corpus-based, empirical and reproducible analyses.
Learning pressures reduce morphological complexity: Linking corpus, computational and experimental evidence
Three lines of evidence converge to show that pressures associated with imperfect language learning are good candidates to causally explain the reduction in morphological complexity in the Latin-to-Romance scenario and that combining corpus, computational and experimental evidence is the way forward in historical linguistics and linguistic typology.
Foreigner-directed speech is simpler than native-directed: Evidence from social media
The corpus data yield inconsistent evidence with respect to the first hypothesis, but largely support the second one, suggesting that foreigner-directed speech is indeed simpler than native-directed.
Linguistic niches emerge from pressures at multiple timescales
It is found that languages spoken in cold, small regions tend to be more complex across a range of linguistic features.


Understanding the Origins of Morphological Diversity: the Linguistic Niche Hypothesis
An agent-based simulation and correlational study show that English-speaking adults who had more interaction with non-native speakers as children showed a relative preference for over-regularized (i.e. morphologically simpler) forms lend support to the linguistic niche hypothesis.
Language Structure Is Partly Determined by Social Structure
The proposed Linguistic Niche Hypothesis hypothesizes that language structures are subjected to different evolutionary pressures in different social environments, and appears to adapt to the environment (niche) in which they are being learned and used.
Language Interrupted: Signs of Non-Native Acquisition in Standard Language Grammars
John McWhorter analyzes how various languages that seem simple but are not creoles, actually are simpler than they would be if they had not been broken down by large numbers of adult learners.
Population Size and Rates of Language Change
Previous empirical studies of population size and language change have produced equivocal results. We therefore address the question with a new set of lexical data from nearly one-half of the world’s
Mixed effect models for genetic and areal dependencies in linguistic typology
To test this hypothesis, Atkinson employs a sample of 504 non-extinct languages from WALS (Haspelmath et al. (eds.) 2008), for which the number of vowels, the number of consonants, and the number of
Language Is a Complex Adaptive System: Position Paper
Language has a fundamentally social function. Processes of human interaction along with domain-general cognitive processes shape the structure and knowledge of language. Recent research in the
This paper is a summary of a research project addressing the question of how L2 speakers in linguistic communities can shape the structure of languages. We present evidence in support for the view
Zipf's law and the grammar of languages: A quantitative study of Old and Modern English parallel texts
A quantitative analysis of the relationship between word frequency distributions and morphological features in languages suggests that the syntheticity of the language in these texts can be captured mathematically, a property the authors tentatively call their grammatical fingerprint.
Innateness and culture in the evolution of language
It is shown that cultural transmission can magnify weak biases into strong linguistic universals, undermining one of the arguments for strong innate constraints on language learning.
