As children advance through school, derived words become increasingly common in their reading materials. Previous studies have shown that children’s knowledge of derivational morphology develops relatively slowly, but there is more to learn about this development. This study examined differences in knowledge of the form and meaning of suffixes across grade levels (Grades 3, 5, and 8) and different types of derivational suffixes (adjectives and nominals). We assessed 309 English-speaking children on word reading and receptive vocabulary tests and two tasks designed to assess the form (orthographic knowledge) and meaning (semantic knowledge) of 28 derivational suffixes (14 adjectives and 14 nominals). Overall, our findings showed a significant improvement in identifying and understanding derivational suffixes from Grade 3 to Grade 5 and a smaller, but still significant, improvement from Grade 5 to Grade 8. Our findings regarding suffix types were mixed. While written forms of adjectives were identified more accurately than nominals across all grades, this advantage did not extend to the students’ understanding of the meaning of the suffixes. These results highlight the distinction between the identification of suffixes and the understanding of their meaning. We discuss our results in relation to suffix frequency in children’s reading materials.

It has long been recognized that the Semitic suffix conjugation and the Berber adjectival perfective suffix conjugation have striking similarities in their morphology, which has been correctly attributed to be the result of a shared inheritance from Proto-Afro-Asiatic. Nevertheless, the function of these conjugations in the respective language families is quite distinct. This article argues that ultimately this suffix conjugation is a predicative suffix in the common ancestor of Berber and Semitic, and moreover shows that Semitic and Berber have significant overlap in the stem formations of adjectives. It is argued that these formations must likewise be reconstructed for their common ancestor.

Combining adjective meaning with the modified noun is particularly challenging for children under three years. Previous research suggests that in processing noun-adjective phrases children may over-rely on noun information, delaying or omitting adjective interpretation. However, the question of whether this difficulty is modulated by semantic differences among (subsective) adjectives is underinvestigated.

A visual-world experiment explores how Italian-learning children (N=38, 2;4–5;3) process noun-adjective phrases and whether their processing strategies adapt based on the adjective class. Our investigation substantiates the proficient integration of noun and adjective semantics by children. Nevertheless, alligning with previous research, a notable asymmetry is evident in the interpretation of nouns and adjectives, the latter being integrated more slowly. Remarkably, by testing toddlers across a wide age range, we observe a developmental trajectory in processing, supporting a continuity approach to children’s development. Moreover, we reveal that children exhibit sensitivity to the distinct interpretations associated with each subsective adjective.

According to a widely held view epistemic justification is a normative notion. According to another widely held assumption, epistemic justification comes in degrees. Given that gradability requires a context-sensitivity that normativity seems to lack, these two assumptions stand in tension. Giving up the assumption of gradability of justification represents a lesser theoretical cost.

Like verbs, adjectives pose a challenge to the young word learner in that some – like red, round, rough, or rectangular – map onto properties that are detectable through the senses, while others – like ready, reasonable, or required – express abstract properties that have no reliable, physical correlate. Even for those adjectives whose properties are observable, how does a child know that one particular property is being highlighted above all others? The physical environment alone will not suffice. Just as with verbs, the child learning adjectives is faced with an inherent indeterminacy of meaning, which can only be resolved through the incorporation of cues originating from multiple sources.

This study investigated whether adult and 3- to 6-year-old native speakers of Russian can use gender-marked adjectives to predict the upcoming noun during sentence comprehension. In a visual world paradigm, participants heard questions (e.g., Где хороший синий ёжик? Gde horošij sinij ëžik? “Where is the nicemasc bluemasc hedgehogmasc?”) including two gender-marked adjectives and a noun while seeing pictures of a target and a distractor of either the same (e.g., ёжик ëžik “hedgehogmasc,” мишка miška “bearmasc”) or different gender (e.g., ёжик ëžik “hedgehogmasc,” собачка sobačka “dogfem”) on the screen. We examined whether participants could use gender-marking anticipatorily (i.e., before the onset of the noun). Mixed-effects logistic regression analyses revealed that both adults and children anticipated the upcoming noun before its onset. The magnitude of the anticipation effect was stronger for adults than children. Subsequent analyses on the child data did not show evidence that age modulated their anticipation ability. The results of this study extend and improve knowledge regarding the role of adjectives that carry a grammatical gender cue in online sentence processing.

Following the Labovian paradigm, the present study uses variationist quantitative methods to examine the linguistic and social factors influencing adjective choices in German. By focusing on adjectives of positive evaluation (such as cool ‘cool’, toll/geil ‘great’), an analysis of over 3,000 tokens reveals that the choice of using one adjective over a competing counterpart is structured systematically. This choice is heavily constrained by the social factor age, with gender also influencing variation to varying degrees. The syntactic position of the adjective also conditions use, with some adjectives favoring predicative position and others favoring attributive or stand-alone position. Comparisons across apparent time, as well as with previous research, indicate that the semantic field of positive evaluation is a perpetually changing locus of variation. By applying variationist methods to German data, the present study illustrates how German lexis can index social meaning, paving the way for future research on German lexical variation. More broadly speaking, this study also contributes to ongoing variationist sociolinguistic research on German language variation and change.*

Adjectives are paradigmatically versatile: they combine with many different items in the same syntactic configuration. They are also syntagmatically versatile: they occur in many different syntactic configurations. Given this versatility, how and to what extent can lexeme-specific preferences and features of the adjectives be identified? With the adjective quick as its starting point, this article answers this question by using corpus data, contrasting the behavior of quick with that of its semantic neighbors. Case study 1 investigates quick's attributive usage. It is shown that quick in its default usage combines with eventive heads, and that there are clear differences in combinatorial preferences across its semantic neighbors. Case study 2 investigates the quick-to-infinitival construction. Here, direct combination with eventive heads is impossible. It behaves differently from other adj-to-infinitival constructions as well as the competing quickly constructions. Comparison of the availability of this construction for quick's semantic neighbors, and linking this to the results of study 1, shows a clear connection between paradigmatic and syntagmatic distributions.

This article investigates prototypically attributive versus predicative adjectives in English in terms of the phonological properties that have been associated especially with nouns versus verbs in a substantial body of psycholinguistic research (e.g. Kelly 1992) – often ignored in theoretical linguistic work on word classes. Inspired by Berg's (2000, 2009) ‘cross-level harmony constraint’, the hypothesis I test is that prototypically attributive adjectives not only align more with nouns than with verbs syntactically, semantically and pragmatically, but also phonologically – and likewise for prototypically predicative adjectives and verbs. I analyse the phonological structure of frequent adjectives from the Corpus of Contemporary American English (COCA), and show that the data do indeed support the hypothesis. Berg's ‘cross-level harmony constraint’ may thus apply not only to the entire word classes noun, verb and adjective, but also to these two adjectival subclasses. I discuss several theoretical issues that emerge. The facts are most readily accommodated in a usage-based model, such as Radical Construction Grammar (Croft 2001), where these adjectives are seen as forming two distinct but overlapping classes. Drawing also on recent research by Boyd & Goldberg (2011) and Hao (2015), I explore the possible nature and emergence of these classes in some detail.

Using ten English adjectives, this study tests the hypothesis that the vowels in adjectives in predicative constructions are longer than those in attributive constructions in spoken conversation. The analyses considered a number of factors: occurrence before a pause, lexical adjective, vowel identity, probability given surrounding words, and others. Two sets of statistical techniques were used: a Mixed-effects model and the Random Forest Analysis based on Conditional Inference Trees (CIT). Both analyses showed strong effects of predicative vs. attributive constructions and individual lexical adjectives on vowel duration in the predicted direction, as well as effects of many of the phonological variables tested. The results showed that the longer duration in the predicative construction is not due to lengthening before a pause, though it is related to whether the adjective is internal or final in the predicative construction. Nor is the effect attributable solely to the probability of the occurrence of the adjective; rather construction type has to be taken into account. The two statistical techniques complement each other, with the Mixed-effects model showing very general trends over all the data, and the Random Forest / CIT analysis showing factors that affect only subsets of the data.

Adjectives are essential for describing and differentiating concepts. However, they have a protracted development relative to other word classes. Here we measure three- and four-year-olds’ exposure to adjectives across a range of interactive and socioeconomic contexts to: (i) measure the syntactic, semantic, and pragmatic variability of adjectives in child-directed speech (CDS); and (ii) investigate how features of the input might scaffold adjective acquisition. In our novel corpus of UK English, adjectives occurred more frequently in prenominal than in postnominal (predicative) syntactic frames, though postnominal frames were more frequent for less-familiar adjectives. They occurred much more frequently with a descriptive than a contrastive function, especially for less-familiar adjectives. Our findings present a partial mismatch between the forms of adjectives found in real-world CDS and those forms that have been shown to be more useful for learning. We discuss implications for models of adjective acquisition and for clinical practice.
