Lexical items consist of noun, adjective, verb, and some adverbs while grammatical items consist of determiner, pronoun, most preposition, conjunction, finite verb, and some classes of adverb.
Why is lexical density important?
Lexical density, then, can serve as a useful measure of how much information there is in a particular text. It can also be used to monitor improvements in the use of lexical items (information carrying-words) in children with under-developed vocabulary and/or word finding difficulties.
What is lexical density How are spoken forms and written forms differ from one another in terms of Density?
In written language, the density means how much the information is presented. Lexical Density is the proportion of lexical items (content words) to the total discourse” (Halliday, 1985:62-63).
What is a good lexical diversity score?
As you can see from the scale above, an adult second language learner would typically have a diversity measure of somewhere between 40-70. An adult native speaker who is writing an academic text who would typically have a measure of between 80-105.
What is type token ratio?
TTR is the ratio obtained by dividing the types (the total number of different words) occurring in a text or utterance by its tokens (the total number of words). A high TTR indicates a high degree of lexical variation while a low TTR indicates the opposite.
What is a good lexical density?
Typically, the lexical density of a written composition is higher than a spoken composition. According to Ure, written forms of human communication in the English language typically have lexical densities above 40%, while spoken forms tend to have lexical densities below 40%.

How is lexical diversity related to vocabulary richness?
“…lexical diversity is about more than vocabulary range. Alternative terms, ‘flexibility’, ‘vocabulary richness’, ‘verbal creativity’, or ‘lexical range and balance’ indicate that it has to do with how vocabulary is deployed as well as how large the vocabulary might be.”
What does the term lexical range and balance mean?
Alternative terms, ‘flexibility’, ‘vocabulary richness’, ‘verbal creativity’, or ‘lexical range and balance’ indicate that it has to do with how vocabulary is deployed as well as how large the vocabulary might be.” In other words, the complexity of a text isn’t just about using a wide variety of vocabulary words.
