Surrey Cross-linguistic Database on Defectiveness

The term 'defectiveness' refers to gaps in inflectional paradigms — specifically,
gaps which do not appear to follow from natural restrictions imposed by meaning
or function. The Cross-linguistic Database on Defectiveness looks
at the prevalence of inflectional defectiveness in a controlled sample of
genetically and geographically diverse language.

术语‘屈折缺陷（defectiveness）’指屈折范式（inflectional paradigms）中的空缺，具体而言，这类空缺并非由语义或功能施加的自然限制所导致。跨语言屈折缺陷数据库（Cross-linguistic Database on Defectiveness）针对遗传谱系与地理分布均呈现多样性的受控语言样本，考察了屈折缺陷的普遍发生率。
