Tiered vocabulary is a pervasive concept in academic scholarship, education policy, and schools. It involves placing individual words into hierarchically arranged tiers, based on their apparent simplicity, sophistication, utility, and complexity, with these categorisations used to determine which words carry value in the classroom. In this article…

High frequency words, which are key to a text, must be mastered to achieve minimum levels of reading proficiency. However, knowledge about the frequency of items in a language is very limited. Given this consideration, WordSift (www.wordsift.org), a word cloud tool based on high frequency and key words can assist English as a Foreign Language…

Published work on vocabulary assessment has grown substantially in the last 10 years, but it is still somewhat outside the mainstream of the field. There has been a recent call for those developing vocabulary tests to apply professional standards to their work, especially in validating their instruments for specified purposes before releasing them…

The words in a language or language variety are often rank ordered in lists that are meant to reflect the relative importance of those words to language users and learners of a language. This rank ordering is done on the basis of the relative prevalence of words in a corpus. Lexical prevalence is often operationalized as measures of frequency,…

Jeff McQuillan offers case studies of intermediate level language learners who read young adult and adult fiction successfully as an argument against explicit vocabulary instruction. Case studies provide useful insights into whatever is being investigated but may not always be generalizable. However, McQuillan's reference to case studies has made…

Despite the vast extent of the English vocabulary, it has been estimated that only around 2400 high frequency word families, which are found on Browne, Culligan, and Phillips' (2013) "New General Service List" (NGSL), make up over 92% of most general English texts. Several studies have shown that a word must be encountered anywhere from…

Computational tools and resources play an important role for vocabulary acquisition. Although a large variety of dictionaries and learning games are available, few resources provide information about the complexity of a word, either for learning or for comprehension. The idea here is to use frequency counts combined with intralexical variables to…

With the advances in technology, wordlists retrieved from computer corpora have become increasingly popular in recent years. The lexical items in those wordlists are usually selected, according to a set of robust frequency and dispersion criteria, from large corpora of authentic and naturally occurring language. Corpus wordlists are of great value…

This paper aims to be an introduction to the General Service List (GSL) that brings together descriptive data with material otherwise dispersed throughout the literature. The discussion first provides an historical overview of the work that scholars, researchers, and educators used as foundations for the manufacturing of the GSL. Following, a…

Averil Coxhead is widely known for developing the Academic Word List, a list of 570 word families associated with great frequency in academic texts. This list has been particularly useful to teachers of English as a Second Language as well as independent learners in tertiary education. She has also developed a Science-based word list (Coxhead and…

This article is a personal view of the application of research on vocabulary to teaching and how there are three different types or categories of relationship between that research and the teaching to which it is applied: first, where the research is not applied or not applied well, second, where it is reasonably well applied, and third, where it…

There is little dispute that formulaic sequences form an important part of the lexicon, but to date there has been no principled way to prioritize the inclusion of such items in pedagogic materials, such as ESL/EFL textbooks or tests of vocabulary knowledge. While wordlists have been used for decades, they have only provided information about…

This article reports on the design and use of a profiler for lexical sophistication (i.e., use of advanced vocabulary), which was created to assess the lexical richness of intermediate and advanced Swedish second language (L2) learners' French and Italian. It discusses how teachers' judgments (TJs) of word difficulty can contribute to the…

This article describes the development and validation of a Vietnamese bilingual version of the Vocabulary Size Test--a test which measures written receptive vocabulary size. The test can be used to measure the English vocabulary size of Vietnamese learners of English. A learner's total vocabulary size is calculated by multiplying their test result…

In China many non-English majors, who often score high on English exams that emphasize reading comprehension and grammar, have difficulty finding the English words they need to express their ideas in speaking and writing. This problem is not unusual, and it is often difficult for students to use their receptive reading and listening vocabulary for…
