Have you ever wondered which language has the most words? It’s a fascinating question, but one that’s incredibly difficult to answer definitively. The complexity arises from various factors, including inflection, multiple meanings, and compound words.
Does English Have the Most Words?
Have you heard language experts say that English has more words than other languages? The claim is made but it’s practically impossible to verify.
Many language experts claim that English has more words than any other language. Steven Frank, author of The Pen Commandments, estimates that English has around 500,000 words, compared to German’s 135,000 and French’s fewer than 100,000. However, these numbers are hard to verify due to the nuances in counting words. For instance, should “run,” “runs,” and “ran” be counted as separate words? What about “run” as a verb and “run” as a noun? According to an NPR article, “run” has at least 645 different meanings!
According to an article from Merriam Webster , English tops a whopping 1 million distinct words, but that those estimates could be off by as much 250,000 words depending on how you include or exclude certain words like chemicals or scientific terms . This vast vocabulary and fluctuation is partly due to English’s history of borrowing words from other languages, including Latin, French, and German. The Oxford English Dictionary, one of the most comprehensive dictionaries, includes nearly 600,000 words.
When counting a language’s words do we count compounds? Is “every day” one word or two? Are the names of new chemical compounds words? Answering the question, “What is the richest language?” becomes more and more complicated.
Estoy, Estás, Está—One Word or Three?
Some languages inflect much more than English. The Spanish verb “estar” has dozens of forms—estoy, estás, está, “I am,” “you are,” “he is” and so on.
Does that make Spanish richer in word count?
Some languages inflect much less (Chinese is famously ending-free). So, whether we count inflected forms will have a huge influence on final counts.
Moreover, many languages habitually build long words from short ones.
German is obvious; it is a trifle to coin a new compound word for a new situation. For example, is the German Unabhängigkeitserklärung—declaration of independence—one word?
Given the possibilities for compounds, German would quickly outstrip English, with the constant addition of new legitimate German “words”, which Germans would accept without blinking.
A Sentence that Translates as One Word
The Turkish language is similar in this way.
Turkish not only crams words together but does so in ways that make whole, meaningful sentences.
“Were you one of those people whom we could not make into a Czechoslovak?” translates as one word in Turkish.
You write it without spaces, pronounce it in one breath in speaking, it can’t be interrupted with digressions, and so forth.
How Many Words in the Dictionary?
Another way of measuring the vocabulary in a language and comparing counts is by counting the number of words listed in a standard authoritative dictionary in that language.
From a list on Wikipedia, here’s one such comparison. This is a list of dictionaries considered authoritative or complete by approximate number of total words or headwords, included. Also figures can vary widely based on dictionary or source.
These figures do not include entries with senses for different word classes (such as noun and adjective) and homographs.
Wikipedia says it’s possible to count the number of entries in a dictionary, but it’s not possible to count the number of words in a language.
| Language | Approximate Number of Headwords |
| Tamil | 1,533,669 |
| Korean | 1,149,538 |
| Portuguese | 818,000 |
| Japanese | 500,000 |
| Italian | 500,000 |
| English | 470,000 |
| Chinese | 378,103 |
| Russian | 220,000 |
| Arabic | 120,000 |
| Spanish | 93,000 |
Which language has the most words? Maybe it’s English.
Rosetta Stone says it’s quite probable that English has more words than most comparable world languages. The reason is historical.
English was originally a Germanic language, related to Dutch and German. English shares much of its grammar and basic vocabulary with those languages.
After the Norman Conquest in 1066 English was hugely influenced by Norman French, which became the language of the ruling class for a considerable period, and by Latin, which was the language of scholarship and of the Church.
Very large numbers of French and Latin words entered the language. This melding of languages means English has a much larger vocabulary than either the Germanic languages or the members of the Romance language family according to Oxford.
English builds its vocabulary through a willingness to accept foreign words. And because English became an international language, it has absorbed vocabulary from a large number of other sources.
Or, Does Arabic Have the Most Words?
Arabic is another contender for the language with the most words. Known for its complexity, a single Arabic word can have multiple meanings, pronunciations, and interpretations. For example, Arabic has hundreds of words for “camel” and several for different stages of love. This richness in vocabulary makes Arabic a strong candidate for the title. There is even a long standing debate that because of it’s root based system Arabic could have over 12 million words. Although many of these roots do not have associated words or meanings. So the actual count is difficult to define and measure.
The National, a leading English-speaking news outlet in the UAE, reports that on average, a single written word in Arabic has three meanings, seven pronunciations, and 12 interpretations. This depth and versatility contribute to Arabic’s reputation as one of the richest languages in terms of vocabulary.
So, which language is richest in words?
Let us ask a different, and we think more important question:
Does it really matter? In some way isn’t counting the number of words just a superfluous exercise?
Whatever languages you translate or interpret in—Chinese, Japanese, Russian, sign language, or others—you are bound to have a rich body of words to work with.
