Why learn Spanish rather than any other language? Because more people speak it as a mother tongue than any language except Mandarin and, by some counts, Hindi; because it is the language of twenty countries, of the fastest-growing part of the United States and of a good slice of the world’s business; because it opens a literature, a cinema and a music that are among the richest anywhere; and because, of all the major languages, it is the one an English speaker learns fastest. This guide puts the case in full, with the figures as they stand today, and ends with what it means for someone learning in London.

Half a billion people, twenty countries

The Instituto Cervantes counted 520 million native speakers of Spanish in 2025 and nearly 636 million people who speak it in all, a figure that grew by 30 million in a single year. It is the official language of twenty countries on four continents, from Spain and Equatorial Guinea to Mexico and Argentina, and the everyday language of a great deal of the twenty-first. Some 24 million people are learning it as a foreign language at any one time, and the number is still rising.

Britain has noticed. The British Council ranks Spanish first among the languages that matter most to the country’s future, ahead of Mandarin, French and Arabic, and in 2025 Spanish overtook French to become the most popular language at GCSE for the first time, having led at A-level since 2019. The generation now entering the workplace chose it, and the generation already there is catching up.

The business case

Spain is the fourth-largest economy in the eurozone, and Spanish companies are a fixture of British life whether or not you have noticed the flag: Santander has been on the high street since it bought Abbey in 2004, ScottishPower belongs to Iberdrola, Zara and its sister brands belong to Inditex of Galicia, and Telefónica bought O2 in 2006. Trade, investment and the lawyers, bankers and accountants who serve them run in both directions, and the meeting after the meeting is in Spanish.

Latin America is the larger prize. Mexico is now the United States’ largest trading partner and the centre of the nearshoring that has moved manufacturing and logistics closer to North America; Colombia, Chile and Peru are steady growth markets for finance, mining, energy and insurance; and Britain’s membership of the CPTPP trade agreement now includes Chile, Peru and Mexico. London firms keep offices in Mexico City, Bogotá, Santiago, Lima and Buenos Aires, and the posting to one of them is how many of our students come to need the language; our guide to working in Latin America covers where the openings are.

What Spanish does in business is not mainly translation. English gets you the meeting; Spanish gets you the relationship, and the Spanish-speaking world does business on relationships. A negotiator who can follow the aside in the corridor, open with the right form of address and answer a joke in kind is trusted sooner and told more. That is the reason companies buy business Spanish training for their people, and the reason the people who have it tend to be the ones sent.

The United States speaks Spanish too

The country Londoners deal with more than any other outside Europe is, by some counts, the second-largest Spanish-speaking country in the world after Mexico. Some 44.9 million people in the United States speak Spanish at home, one person in seven over the age of five, and the Hispanic population passed 65 million, a fifth of the country. Two national television networks broadcast in Spanish, Miami runs much of Latin America’s business from Florida, and American popular culture increasingly arrives in Spanish: the most-streamed artist in the world in 2025 sang in it, and so did the Super Bowl half-time show of 2026. For anyone whose work touches the American market, Spanish is the country’s second business language, and it is not a distant second.

What opens up

The practical case is strong, and it is not the reason most of our students give. They want the thing itself. Spanish is the language of Cervantes, of García Márquez and Neruda, of Bolaño, Allende and Vargas Llosa, and a translation of any of them is a copy of a painting. It is the language of Almodóvar and of an Argentinian cinema with two Oscars to its name, of La casa de papel, for a time the most-watched non-English series in Netflix’s history, of flamenco, tango, salsa and reggaeton, and of the commentary on half the world’s football. Hearing any of it in the original is a different experience from reading it in subtitles, as anyone who has understood their first joke in Spanish will tell you, and the expressions that don’t translate are exactly the ones worth learning.

Then there is the travel. Spain is the most visited country by British holidaymakers, and Spanish turns a fortnight there from a transaction into a conversation; it does the same in Mexico, Colombia, Peru, Argentina and everywhere between. And for the many Londoners with a Spanish-speaking partner, in-laws or grandparents, it is the difference between attending the family dinner and being part of it.

What it does for your brain and your CV

Learning a language is the one hobby with a clinical literature. People who use two languages have been found in study after study to switch between tasks better, to filter distraction better and, most strikingly, to show the first symptoms of dementia several years later on average than people who use one. A second language also improves the first: learners who have had to think about Spanish verb endings and word order write clearer English, because they have noticed their own language for the first time.

On a CV, Spanish is the language employers can actually use. It is the second language of the world’s largest economy and the first language of the twenty countries above, and unlike most languages it is one a British professional can reach a working level in within a year of steady lessons, which is what how long it takes to learn Spanish sets out.

The Spanish-speaking internet

Spanish is the second most common language of the web’s content, used by 6 per cent of all websites against English’s 49.5 per cent and ahead of German, Japanese and French, and by number of users it is the third most used language online after English and Chinese. For a learner that means a bottomless supply of material on any subject you already care about, from your industry’s trade press to your football club’s Spanish-language fan sites, and the easiest exercise there is: switch your phone, your search engine and one news app to Spanish and let the words come to you. Our guide to dictionaries, apps and translators covers the tools for reading it.

The easiest of the big languages for an English speaker

None of the above would count for much if Spanish took a decade. It does not. Thousands of words are near enough to English to be recognised on sight, the spelling is regular, the pronunciation is consistent and the grammar follows familiar lines, which is why Spanish is one of the easiest languages for English speakers to learn. The traps are known and few, the false friends chief among them, and a beginner with a weekly lesson is holding a conversation within a few months. Whichever accent of Spain or Latin America you end up needing, the language you learn is the same one.

Why London is a good place to do it

Spanish is the second most common language in London after English apart from Romanian, spoken at home by about 117,000 people, and the Colombian cafés, tapas bars, language exchanges and film festivals that come with them are listed in our guide to practising Spanish in London. The practice is here; the lessons come to you. Private Spanish lessons take place at your home or your office with a native-speaker tutor, online Spanish lessons keep the same tutor when you travel, and an intensive Spanish course compresses the first months into weeks when there is a posting or a move to prepare for.

Questions people ask

Is Spanish more useful than French or Mandarin for a British professional? For most, yes. It has more native speakers than French and is far quicker to learn than Mandarin, it is spoken across two continents and much of a third, and the British Council’s ranking puts it first for the UK on exactly those grounds.

Everyone I deal with speaks English. Do I need it? English will get you through the meeting. Spanish gets you the conversation before and after it, where the relationship is made, and it is the difference between the supplier who is tolerated and the one who is trusted.

Which Spanish should I learn? Standard Spanish first; it is understood everywhere. Choose the accent by destination, and a native-speaker tutor can teach the Spanish of Madrid, Mexico City or Buenos Aires from the first lesson.

How long will it take? Conversation within a few months of weekly lessons; a working level within the first year for anyone who speaks from the first week; faster still with an intensive course before a deadline.

Start with the first lesson

The case for Spanish is the size of the world it opens: half a billion people, twenty countries, the second language of the United States and a Spanish-speaking community of well over 100,000 on your doorstep in London. What turns that into a reason is a first lesson with someone who speaks it, and the months of conversation that follow. That is what we do.
