Vocabulary

At its simplest, “vocabulary” refers to the total number of words a person understands and could use to communicate information and experiences. The words may be in verbal, printed, or visual form.

People know far more words than they actually use in the day-to-day processes of communication, such as conversation or social media engagement. For instance, a person may know the word “substantial”—that word is technically part of their vocabulary—but it may not be part of their working vocabulary. In conversation or in written communication, that person is far more likely to use “large,” a synonym for the word but a term far more people would recognize.

Communication studies that focus on vocabulary look at two critical issues: the difference between the words a person knows and the words a person actually uses (passive versus active vocabularies), and the reasons why the size of a person’s vocabulary tends to reach its fullest number at a relatively early age.

Background

Because words are among the most common and foundational ways to transmit information, ideas, opinions, and experiences, vocabulary skills affect virtually every aspect of a person’s life. Communication confidence is an intrinsic element, for instance, of academic and professional success. More importantly, vocabulary competence is a foundational skill in everyday conversation and in the most basic exchanges transmitting information, from getting directions to following a recipe. Vocabulary skills are an element of full reading comprehension, clear writing, active listening, and clear and effective speech or use of sign language.

There are multiple levels of word knowledge, from recognition of the word (that is, the particular combination of vowels and consonants and its pronunciation), to understanding its meaning and connotations in context (definition), to being able to use the word confidently, grammatically, and appropriately.

Words vary in complexity. The simplest are common nouns and verbs that describe actions. More complex words include those with multiple meanings, those that are used infrequently but may be understood in context, and those with logically abstract meanings. The most sophisticated words are particular to a specific discipline or subject area, such as scientific, mathematical, legal, or medical terms.

Building a vocabulary is most often associated with school-aged children, people learning a new language, and those in specialized training. Understanding the smallest components of words that convey meaning, known as “morphemes,” can be integral to building vocabulary. Morphemes include prefixes, suffixes, and small “base” words.

People rely on many ways of growing their vocabularies. Extensive reading, rote memorization, and association building are some of the most common approaches. Writing drills and word matching serve as memorization aids. Strategies for vocabulary building by association include conversation, learning by doing, use of sophisticated words in context, storytelling, sorting and grouping items, using art or props, guided play and games, connecting new words to existing vocabulary, learning common roots for words, talking about books, and summarizing and paraphrasing passages. Regardless of the method employed, repeat exposure to a word and proper explanation of it are crucial.

Most English-speaking children master a vocabulary of about four thousand words by five years of age. That vocabulary range then grows by roughly three to four thousand words annually throughout primary and secondary school years. Native speakers are estimated to have acquired knowledge of fifty thousand English word families (including the words’ various derivations) by the twelfth grade, on average. The rate of vocabulary building then appears to drop off to a few hundred per year through middle adulthood.
