How Many Words Are in the English Language? A Clear and Complete Explanation

The reason there is no exact number of English words

The English language has been evolving in the world and this has taken a long period of over 1,500 years to absorb the words of most of the languages such as Latin, French, Greek, Norse, Arabic, and Hindi. Since this history is long and varied, the English vocabulary is enormous and stratified. Words are introduced into the language by science, technology, pop culture, slang, and even brand names, and more ancient words become forgotten and fall into obscurity.

The greatest difficulty is how one can tell what really constitutes a word. Would we not count grammatical variations such as talk, talks, talked and talking as distinct words, or as a single root word? What of complex words, shortenings, technicalities or slang? The various strategies give quite different totals.

Dictionary Estimates and What They Mean

The majority of word-count estimates are provided by dictionaries, however, dictionaries differ.

English dictionaries have estimated between 170 and 470 thousand commonly known words today. The number of English words that are recorded in total goes way beyond 600,000 when old words, jargon (scientific), jargon (legal), jargon (medical) and jargon (historical) are factored in. There are linguists who believe that with the inclusion of all technical and specialized words, English can have more than a million words.

These numbers do not contradict each other; they are just different methods and purposes of counting.

What Does Count as a Word?

A decision on whether a term is to be taken as a word is determined by a number of factors:

• Root words vs. word forms: There are those in which all forms are counted as one, and there are those in which they are counted separately.

• Technical and scientific language: Fields such as chemistry and medicine alone add hundreds of thousands of technical terms.

• Slang and colloquialism: The Internet culture is continuously coining new terms, some of which gain permanence.

• Regional and dialect: British, American, Australian, Indian, etc. all introduce new words.

• Overdue and archaic words: Words that are no longer in use in the present day English can be found in history.

Since English is so lenient, it readily incorporates new words without having to be legally endorsed.

The Question of How Many Words Does the Average Person Use

However, not a single person speaks all of the English vocabulary. Research shows that:

• Average native speaker of English is an active user of the English language who actually knows between 20,000 and 35,000 words.

• An adult educated person can identify 50,000 words or more.

• Ordinary everyday communication is normally based on 5,000 to 7,000 words a day.

This is to say that the huge number of words in the English language is more of a communal language resource than of an individual mastery.

Should or Shouldn’t the English Language Be Growing?

Yes—rapidly. In fact, new words and words that have new meanings are introduced every year as a result of technological progress, science, social trends and cross-border communication. Although not every one of these words remains long term, lots of them remain permanent in the language.

English has only been growing as it is spoken everywhere and it has the ability to accommodate a new thought and culture with ease.
