Examining the dimensionality of vocabulary in English as a second language in Chinese children

Open access
Xie, Qiuzhi, Yeung, Susanna Siu-Sze·2025·Journal of Child Language

Abstract

This study compared a unidimensional model of vocabulary and a two-factor model comprising vocabulary breadth and depth in a second language (L2). A total of 167 Chinese Grade 4 and 5 primary school children (Mean age = 9.96 years old) learning English as an L2 participated in this study, and they were tested on four English vocabulary tests. Our results of confirmatory factor analyses indicate that vocabulary breadth and depth were not two distinct dimensions, and the unidimensional model was supported. Theoretical and practical implications were discussed.

  • Morphological compounding contributes to syntactic skills by possibly facilitating the understanding of word order and sentence structure.

    “In addition, morphological compounding contributes to syntactic skills by possibly facilitating the understanding of word order and sentence structure (Xie & Yeung, 2024).”

    From Do word-level skills show cross-linguistic transfer and predict bilingual reading? (2026) · cites this paper as Xie & Yeung, 2024

    The Introduction discusses vocabulary breadth and depth, while the Discussion passage concerns elaborating word meanings; neither addresses morphological compounding as a contributor to syntactic skills. Searches for compounding, word order, sentence structure, and syntactic awareness found no passage supporting the proposed mechanism. Page numbers were not available in our copy. (LLM, conf=0.73)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
