A person's vocabulary is the set of words they are familiar with in a language. A vocabulary usually grows and evolves with age, and serves as a useful and fundamental tool for communication and acquiring knowledge.
A vocabulary is defined as "all the words known and used by a particular person".[1] However, the words known and used by a particular person do not constitute all the words a person is exposed to. By definition, a vocabulary includes the last two categories of this list:[2]
Listed in order of most ample to most limited:[3][4]
A person's reading vocabulary is all the words he or she can recognize when reading. This is the largest type of vocabulary simply because it includes the other three.
A person's listening vocabulary is all the words he or she can recognize when listening to speech. This vocabulary is aided in size by context and tone of voice.
A person's writing vocabulary is all the words he or she can employ in writing. Contrary to the previous two vocabulary types, the writing vocabulary is stimulated by its user.
A person's speaking vocabulary is all the words he or she can use in speech. Due to the spontaneous nature of the speaking vocabulary, words are often misused. This misuse – though slight and unintentional – may be compensated by facial expressions, tone of voice, or hand gestures.
"Focal vocabulary" is a specialized set of terms and distinctions that is particularly important to a certain group; those with a particular focus of experience or activity. A lexicon, or vocabulary, is a language's dictionary, its set of names for things, events, and ideas. Some linguists believe that lexicon influences people's perception on things, the Sapir–Whorf hypothesis. For example, the Nuer of Sudan have an elaborate vocabulary to describe cattle. The Nuer have dozens of names for cattle because of the cattle's particular histories, economies, and environments. This kind of comparison has elicited some linguistic controversy, as with the number of "Eskimo words for snow". English speakers can also elaborate their snow and cattle vocabularies when the need arises.[5][6]
Initially, in the infancy phase, vocabulary growth requires no effort. Infants hear words and mimic them, eventually associating them with objects and actions. This is the listening vocabulary. The speaking vocabulary follows, as a child's thoughts become more reliant on its ability to express itself without gestures and mere sounds. Once the reading and writing vocabularies are attained – through questions and education – the anomalies and irregularities of language can be discovered.
In first grade, an advantaged student (i.e. a literate student) knows about twice as many words as a disadvantaged student. Generally, this gap does not tighten. This translates into a wide range of vocabulary size by age five or six, at which time an English-speaking child will know about 2,500–5,000 words. An average student learns some 3,000 words per year, or approximately eight words per day.[7]
After leaving school, vocabulary growth reaches a plateau. People may then expand their vocabularies by engaging in activities such as reading, playing word games, and participating in vocabulary programs.
Even if we learn a word, it takes a lot of practice and context connections for us to learn it well. A rough grouping of words we understand when we hear them encompasses our "passive" vocabulary, whereas our "active" vocabulary is made up of words that come to our mind immediately when we have to use them in a sentence, as we speak. In this case, we often have to come up with a word in the timeframe of milliseconds, so one has to know it well, often in combinations with other words in phrases, where it is commonly used.
Native speakers' vocabularies vary widely within a language, and are especially dependent on the level of the speaker's education. A 1995 study estimated the vocabulary size of college-educated speakers at about 17,000 word families, and that of first-year college students (high-school educated) at about 12,000.[10]
Francis and Kucera[11] studied texts totaling one million words and found that if one knows the words with the highest frequency, they will quickly know most of the words in a text:
| Vocabulary Size | Written Text Coverage |
|---|---|
| 1000 words | 72.0% |
| 2000 | 79.7 |
| 3000 | 84.0 |
| 4000 | 86.8 |
| 5000 | 88.7 |
| 6000 | 89.9 |
| 15,851 | 97.8 |
By knowing the 2000 words with the highest frequency, one would know 80% of the words in those texts. The numbers look even better than this if we want to cover the words we come across in an informally spoken context. Then the 2000 most common words would cover 96% of the vocabulary.[12] These numbers should be encouraging to beginning language learners, especially because the numbers in the table are for word lemmas and knowing that many word families would give even higher coverage.
Learning vocabulary is one of the first steps of learning a second language, yet a learner never finishes vocabulary acquisition. Whether in one’s native language or a second language, the acquisition of new vocabulary is a continuous process. Many methods can help one acquire new vocabulary.
Although memorization can be seen as tedious or boring, associating one word in the native language with the corresponding word in the second language until memorized is considered one of the best methods of vocabulary acquisition. By the time students reach adulthood, they generally have gathered a number of personalized memorization methods. Although many argue that memorization does not typically require the complex cognitive processing that increases retention (Sagarra & Alba, 2006)[13], it does typically require a large amount of repetition. Other methods typically require more time and longer to recall.
Some words cannot be easily linked through association or other methods. When a word in the second language is phonologically or visually similar to a word in the native language, one often assumes they also share similar meanings. Though this is frequently the case, it is not always true. When faced with a false cognate, memorization and repetition are the keys to mastery. If a second language learner relies solely on word associations to learn new vocabulary, that person will have a very difficult time mastering false cognates. When large amounts of vocabulary must be acquired in a limited amount of time, when the learner needs to recall information quickly, when words represent abstract concepts or are difficult to picture in a mental image, or when discriminating between false cognates, rote memorization is the method to use. A neural network model of novel word learning across orthographies, accounting for L1-specific memorization abilities of L2-learners has recently been introduced (Hadzibeganovic & Cannas, 2009).[14]
One useful method to build vocabulary in a second language is the keyword method. When additional time is available or one wants to emphasize a few key words, one can create mnemonic devices or word associations. Although these strategies tend to take longer to implement and make take longer in recollection, they create new or unusual connections that can increase retention. The keyword method requires deeper cognitive processing, thus increasing the likelihood of retention (Sagarra & Alba, 2006)[13]. This method uses fits within Paivio’s (1986)[15] dual coding theory because it uses both two verbal and image memory systems. However, this method should be used only with words that represent concrete and imageable things. Abstract concepts or words that do not bring a distinct image to mind are difficult to associate. In addition, studies have shown that associative vocabulary learning is more successful with younger aged students (Sagarra & Alba, 2006)[13]. As students advance and age, they tend to rely less on creating word associations to remember vocabulary.
Several word lists have been developed to provide people with a limited vocabulary either quick language proficiency or an effective means of communication. In 1930, Charles Kay Ogden created Basic English (850 words). Other lists include Simplified English (1000 words) and Special English (1500 words). The General Service List,[16] 2000 high frequency words compiled by Michael West from a 5,000,000 word corpus, has been used to create a number of adapted reading texts for English language learners. Knowing 2000 English words, one could understand quite a lot of English, and even read a lot of simple material without problems.
James Flynn reports the remarkable differences in vocabulary exposure of pre-schoolers between different classes in the U.S.A. Apparently, pre-schoolers of professional families are typically exposed to 2,150 different words, pre-schoolers from working class families to 1,250 words, while those from households on welfare just 620.[17]
