Abstract:

Based on a dataset representing close to 3/4 of the world’s languages we investigate differences among languages and between items on the Swadesh list with regard to mean word length. Mapping the world-wide distribution of word length shows convergence at a continent-wide level, a Pacific Rim signature, and a tendency for large word length averages to be a recessive trait. The amount of data, which is unparalleled in previous, related studies allows us to provide more solid estimates and accounts for the interrelationships between word length, phoneme segment inventory size, and population size than was previously possible. Word length differences between items exhibit robust, universal tendencies, which are discussed in relation to other quantities, including stability, synonymy, and attestation.


讲座大意:

        基于一个代表世界近3/4语言的数据集,我们调查了不同语言之间以及斯瓦迪士词表上词项之间在平均字长方面的差异。绘制世界范围的词长分布图表明,在整个大陆的水平上存在趋同,这是环太平洋地区的特征,而且大词长平均值是一种隐性特征。大量的数据,这在以前的相关研究中是无与伦比的,这使我们能够提供比以前更可靠的估计,并解释单词长度、音素片段清单大小和总体大小之间的相互关系。词条之间的词长差异表现出强烈的普遍趋势,这一趋势与其他数量有关,包括稳定性、同义词和证明。
