Lexical richness is one of the dimension of quantitative analysis of the lexical structure. It is also known as vocabulary richness or lexical diversity, lexical sophistication, linguistic variability. There are many measures that have been used for calculating lexical richness. One of the popular measure used for calculating lexical richness is based on the ratio of different words (Types) to the total number of words (Tokens) known as the Type-Token Ratio (TTR).Sometimes lexical richness is measured by the square root variants of TTR and other indices. Quantitative Analysis of the text with the help of TTR and its variant indicate the organization of texts and behavior of the lexical frequency, quantitative text analysis, authorship attribution and quantitative stylistics. This paper is organized in four sections, The first section introduces the approaches of lexical richness along with the significance. Second section discusses the various existing lexical richness approaches and techniques which are TTR-based measures. In third section detailed review of literature is conducted to explore the work related to lexical richness and it's applied aspects in various discipline. Fourth section presents the concluding remark.
