We examined how language supports the expression of temporality within sentence boundaries in English, which has a rich inventory of grammatical means to express temporality. Using a computational model that mimics how humans learn from exposure we explored what the use of different tense and aspect (TA) combinations reveals about the interaction between our experience of time and the cognitive demands that talking about time puts on the language user. Our model was trained on n -grams extracted from the BNC to select the TA combination that fits the context best. It revealed the existence of two different sub-systems within the set of TA combinations, a “simplex” one that is supported lexically and is easy to learn, and a “complex” one that is supported contextually and is hard to learn. The finding that some TA combinations are essentially lexical in nature necessitates a rethink of tense and aspect as grammatical categories that form the axes of the temporal system. We argue that the system of temporal reference may be more fruitfully thought of as the result of learning a system that is steeped in experience and organised along a number of functional principles.

Usage-based linguistics postulates that multi-word expressions constitute a substantial part of language structure and use, and are formed through repeated chunking and stored as exemplar wholes. They are also re-used to produce new sequences by means of schematization. While there is extensive research on multi-word expressions in many spoken languages, little is known about the status of multi-word expressions in the mainstream U.S. variety of American Sign Language (ASL). This paper investigates recurring multi-word expressions, or sequences of multiple signs, that involve a high-frequency sign of visual perception glossed as look and the family of ‘look’ signs. The look sign exhibits two broad functions: look /‘vision’ references literal or metaphorical vision and look /‘reaction’ signals a person’s reaction to a visual stimulus. Data analysis reveals that there are recurring sequences in distinct syntactic environments associated with the two functions of look , suggesting that look is in the process of grammaticalization from a verb of visual perception to a stance verb. The sequences demonstrate the emergence of linguistic structure from repeated use through the domain-general cognitive process of chunking in ASL.

Linguists have debated whether complex prepositions deserve a constituent status, but none have proposed a dynamic model that can both predict what construal a given pattern imposes and account for the emergence of non-spatial readings. This paper reframes the debate on constituency as a justification of the constructional status of complex prepositional patterns from a historical perspective. It focuses on the Prep NP IL of NP lm construction, which denotes a relation of internal location between a located entity (a trajector) and a reference entity (a landmark). Four subschemas of the Internal Location construction are examined: middle cxn ( in the middle of ), center cxn ( in/at the center of ), heart cxn ( in/at the heart of ), and midst cxn ( in the midst of ). All occurrences are extracted from the COHA, along with their co-occurring landmark NPs. Using vocabulary growth curves, all patterns are shown to be productive over the whole period covered by the corpus, although at different levels. Using word2vec , a semantic vector space with the landmark collocates of each pattern is made. Curves indexed on association scores are plotted to see how densely semantic areas have been populated across four consecutive periods: 1810s–1860s, 1870s–1910s, 1920s–1970s, and 1980s–2000s. Two divisions of labor have emerged. midst cxn and heart cxn are in complementary distribution and operate mostly at the level of abstract locations whereas middle cxn and center cxn are in parallel distribution and operate at the level of concrete locations.

This study describes metonymic argument alternations, in which a constructional slot can be filled by any of a set of semantic roles that index one another, and provides a diachronic corpus analysis of two such alternations in French. In the Reveal secret frame and other communication frames, the Medium can indexically replace the Speaker and the Topic can indexically replace the Information. A regression analysis shows that while topic for information metonymy is more syntactically and pragmatically restricted, medium for speaker metonymy has seen an increase in usage over time across the frame. This change is related to sociocultural developments and has implications for the study of figurative language and lexical semantic change. While it is well understood that figurative mechanisms such as metonymy affect language change, here it is demonstrated that cultural shifts drive changes in metonymies themselves, with corresponding impacts for linguistic structure.

Words are processed more easily when they have canonical phonotactic shapes, i.e., shapes that are frequent both in the lexicon and in usage. We explore whether this cognitively grounded constraint or preference implies testable predictions about the implementation of sound change. Specifically, we hypothesise that words with canonical shapes favour, or ‘select for’, sound changes that (re-)produce words with the same shapes. To test this, we investigate a Middle English sound change known as Open Syllable Lengthening (OSL). OSL lengthened vowels in disyllables such as ME /ma.kə/ make , but more or less only when they became monosyllabic and when their vowels were non-high. We predict that word shapes produced by this implementation pattern should correspond to the shapes that were most common among morphologically simple monosyllables and disyllables at the time when OSL occurred. We test this prediction against Early Middle English corpus data. Our results largely confirm our prediction: monosyllables produced by OSL indeed conformed to the shapes that were most frequent among already existing monosyllables. At the same time, the failure of OSL to affect disyllables (such as body) prevented them from assuming shapes that were far more typical of morphologically complex word forms than of simple ones. This suggests that the actuation and implementation of sound changes may be even more sensitive to lexical probabilities than hitherto suspected. Also, it demonstrates how diachronic data can be used to test hypotheses about constraints on word recognition and processing.
