Abstract

This study examines the lexical development of two Turkish sisters (aged 1;4 and 2;3) and measures their lexical diversity in spontaneous production data. It suggests that the dependence of the TTR (type-to-token ratio) on the token size may indicate differential levels of lexical diversity. To measure the decrease in the TTR with respect to the increasing token size, it provides a method based on Herdan’s Log TTR. The noun TTR is found to be higher than the TTR of other lexical categories in the data, implying the prevalence of nouns in early lexicon until a sharp increase in the verb TTR around 2;3.
