English in five numbers

About 1.5 billion people speak English, and over 390 million of them as their native language, according to Britannica. Do the subtraction and you see what makes English unusual: roughly three out of four people who speak it learned it. As a learner, you are not an outsider — you are in the majority.

1. It is the language people use across borders

Britannica calls English the first choice of foreign language in most countries of the world — which is exactly what made it a global lingua franca. When a Turkish engineer meets a Brazilian client, or a Moroccan nurse talks to a Dutch patient, English is usually the language they try first. Learning it gives you one language for many countries; our guide Where is English spoken? shows them on a map.

2. Half of the web is written in it

In November 2026, W3Techs found English on 49.5% of the websites whose content language it could identify. The next languages are far behind: Spanish 6.1%, German 5.9%, Japanese 4.9%, French 4.6%, Portuguese 4.1% — Turkish 1.6%, Arabic 0.6%. For many subjects, the most complete manual, course or forum thread is in English. Reading English turns the web from a shelf into a library.

3. Ships and planes run on it

At sea, the International Maritime Organization adopted its Standard Marine Communication Phrases in November 2001 (resolution A.918(22)). They are built on basic English, because English was agreed as the common language for navigation where language difficulties arise — and under the STCW convention, officers in charge of a navigational watch on ships of 500 gross tonnage or more must be able to understand and use them.

In the air, ICAO runs language proficiency requirements for pilots and air-traffic controllers; its Assembly adopted Resolution A38/8 in 2013 on proficiency in the English used for radio communications. If you want to work at sea, in aviation or around ports and airports, English is part of the job.

4. International organisations work in it

The United Nations has six official languages — Arabic, Chinese, English, French, Russian and Spanish — and delegates may speak any of them. Yet the UN itself has had to ask for an end to “the disparity between the use of English and the use of the other five”: inside large organisations, English is the language used most. The IMO, for example, works in English, French and Spanish.

5. Classmates and colleagues already learned it

In 2024, according to Eurostat, 82.5% of primary pupils in the EU were learning English, 97.6% in lower-secondary school and 89.4% in upper-secondary (96.3% in general programmes, 81.1% in vocational ones). The people you will study or work with in Europe very likely have school English — your English is what connects you to them.

6. It opens study and job options

If a course, a job or a scholarship you want asks for English, look for the level it names — a CEFR level (A1 to C2) or a test score — and measure yourself against it: the free English level test gives an estimate from A1 to B2 in about eight minutes.

7. It is easier than its reputation

English grammar has few endings. Adjectives never change — the tall man, the tall woman, where Spanish says el hombre alto, la mujer alta — and a verb like ride has only five forms (ride, rides, rode, riding, ridden); German reiten has 16, according to Britannica. The hard parts are elsewhere: spelling that no longer matches the sounds, and many irregular verbs. Our guides on English grammar basics, English tenses and the history of English explain both.

First step: take the free English level test — 24 questions, no sign-up. Under “I speak”, choose your own language and the questions come in it.
