Of the 1.5 billion English speakers in the world, over half learned it as a second or additional language.

The “language of business”, English has become a foundational skill for anyone looking to work in an international business or at a leadership level, and many English as a Second Language (ESL) speakers find themselves working in English on a daily basis.

But working in your second or third language comes with a unique set of challenges and opportunities.

We spoke to five global leaders about the role English has played in their careers, the challenges of being an ESL speaker, and how businesses can create a culture where everyone has a voice.

A passport to leadership

Strong English skills open doors. More than three-quarters of people with advanced English skills are in senior or leadership roles, compared to just 32% of those with limited English proficiency.

ɫèAV Languages CTO, , describes English as a “passport for this new world of opportunities, opening many, many doors I wouldn’t have had access to.”

There’s a cumulative effect, with one door opening and leading to the next.

Brushing up on his English skills was the spark that won Perrucci a scholarship to Denmark. That semester blossomed into a six-year stay, multiple degrees, his first international job opportunity, and a career with well-known global brands.

Whether it was getting onto a top MBA program or that first role at a big international company, for all the leaders we spoke to, English has proved to be a career catalyst.

More diversity, more innovation, more revenue

For companies looking to innovate and stand out in a competitive global market, an international team is essential.

“We’re aiming to build models of childcare that don’t exist at the moment”, explains Founder and CEO, .

“To do that, we need diversity of thought. With an international team, it’s more likely that someone will say “hey, I was living in Cape Verde for a while, and I saw this interesting thing”.

It’s an approach that pays off. found that businesses with more diverse management teams are more innovative, leading to 19% higher revenues.

Global customers, global team

A more diverse team can also help businesses stay close to their customers.

As technology has made it easier to operate across multiple countries, businesses quickly find themselves responding to the different needs, preferences, and expectations of customers all over the world.

“Reflecting the global nature of our business in our workforce means we can build a better, more effective service and a more successful business as a result”, explains , CEO of .

To help them stay close to their 5.2 million members across 420 cities, Zeeck’s team at InterNations is made up of more than 50 different nationalities.

English is the main language both for the InterNations team and platform, helping them create “a sense of oneness and community by using a shared language”.

The ultimate brain training

The leaders we interviewed spoke, on average, four languages, with many working across multiple languages on a day-to-day basis.

That experience of jumping between different languages also develops important leadership skills.

“When you speak multiple languages,” explains Perrucci, “different parts of the brain have to work together and make connections… It teaches your brain to be flexible about what you see and the way you interpret it”.

Zeeck likened it to working out: “Just as going to the gym improves your physical wellbeing, the mental challenge of learning a new language is good exercise for the brain”. It’s one of the reasons he provides all of his team language training.

The mental load of language

But hopping between languages and navigating different cultural nuances can take its toll.

“People whose first language is English often overlook the computing power it takes to work in your second or third language,” explains, Managing Director of International Wellbeing,, who only spends around a third of his time speaking his mother tongue.

“Even when colleagues are fluent in the language you're communicating in, it might still take them a bit more energy than you expect”, he continues. “By Friday afternoon, for example, I’m struggling to think fluently in whichever language!”.

The challenge of speaking up

For those who are less confident in their English skills, it can significantly impact the way they contribute at work.

Less than half (48%)of ESL speakers feel comfortable speaking up at work, andonly 10%of employees with limited English proficiency felt they could express themselves fully at work.

The dynamic can change depending on who’s in the room. “I see the difference when ESL speakers are on calls with confident, fluent English speakers”, adds, CEO and Founder of.

“They speak less”, she continues, “they caveat their contributions with “I might be wrong”, and you can see their English actually worsens because they feel more stressed”.

Without the right culture and support, businesses miss out on the benefits of an international team they’ve recruited.

Conscious leadership

The task of building a team and helping overcome the challenges of global working falls to business leaders.

The five leaders we spoke to shared practical tips for supporting global teams, including acknowledging and proactively addressing differences, avoiding interrupting ESL speakers, and using voice notes for sensitive communication to allow tone and emotion to come through.

More fundamentally, ESL speakers need business leaders to build a culture where it’s ok to make mistakes.

Leaders with first-hand experience of being an ESL speaker are uniquely placed to understand their increasingly global teams, pre-empt their challenges, and nurture a culture that allows difference to shine.

The journey from local roles to global leadership positions hinges on strong communication skills. The stories shared by our leaders demonstrate how English proficiency not only unlocks individual career potential but also drives organizational success through innovation and diverse perspectives. By fostering a culture that values and supports language learning, businesses can harness these benefits, ensuring their teams are prepared to excel on the global stage.

    How the English language has changed over the decades

    By Steffanie Zazulak

    All languages change over time, and there can be many different reasons for this. The English language is no different – but why has it changed over the decades?

    Some of the main influences on the evolution of languages include:

    • The movement of people across countries and continents, for example, migration and, in previous centuries, colonization. For example, English speakers today would probably be comfortable using the Spanish word 'loco' to describe someone who is 'crazy'.
    • Speakers of one language coming into contact with those who speak a different one. No two individuals speak identically: people from different geographical places clearly speak differently and even within the same community there are variations according to a speaker’s age, gender, ethnicity and social and educational background. For example, the word 'courting' has become 'dating'.
    • New vocabulary required for inventions such as transport, domestic appliances and industrial equipment, or for sporting, entertainment, cultural and leisure reasons. For example, the original late 19th century term 'wireless' has become today’s 'radio'.

    Due to these influences, a language always embraces new words, expressions and pronunciations as people come across new words and phrases in their day-to-day lives and integrate them into their own speech.

    What changes has the English language seen?

    As the English language has changed, it’s been easy to pick out words that pass into common usage. Here at ɫèAV English, we have explored some of these recent changes to the English language. The rise in popularity of internet slang has seen phrases such as 'LOL' (Laugh Out Loud), 'FOMO' (Fear Of Missing Out) and 'fam' (an abbreviated form of family) become firmly embedded in the English language over the past ten years.

    Every decade sees new slang terms like these appearing in the English language. And while some words or abbreviations do come from internet or text conversations, others may appear as entirely new words, a new meaning for an existing word, or a word that becomes more generalized than its former meaning, brought about by any one of the reasons above. Decades ago, 'blimey' was a new expression of surprise, but more recently 'woah' is the word in everyday usage.

    Sentence structure is of course, another change to the English language. Decades ago, it would have been normal to ask 'Have you a moment?' Now, you might say 'D’you have a sec?' Similarly, 'How do you do?' has become 'How’s it going?' Not only have the sentences been abbreviated, but new words have been introduced to everyday questions.

    Connected to this is the replacement of certain words with other, more modern versions. It’s pretty noticeable that words like 'shall' and 'ought' are on the way out, but 'will', 'should' and 'can' are doing just fine.

    Other changes can be more subtle. Many verbs can take a compliment with another verb in either the '-ing' form or the 'to' form, for example, 'they liked painting/to paint', 'we tried leaving/to leave', or 'he didn’t bother calling/to call'. Both of these constructions are still used and have been for a long time, but there has been a steady shift over time from the 'to' to the '-ing' compliment.

    What do the changes mean?

    There are many other changes to the English language – what have you noticed? Have these changes affected your teaching or learning methods?

    Most contemporary linguistic commentators accept that change in language, like change in society, is inevitable. Some think that is regrettable, but others recognize it as a reinvigoration of a language, bringing alternatives that allow subtle differences of expression.

    Linguist, writer and lecturer David Crystal considers whether 'text speak' is undermining the English language. His response to the naysayers who claim it is damaging the English language is to point out that abbreviations have been around for a long time. While some, such as the ones we discussed above, are new, others, such as the use of 'u' for 'you' and the number 8 as a syllable in 'later', have been around for a century or more. Further to this, research shows that there is a correlation between the ability to use abbreviations and the ability to spell. After all, in order to abbreviate, you have to know which letters to abbreviate.

    As with everything, change isn’t necessarily a bad thing and, as the needs of English language users continue to change, so will the language.

    Being bilingual can help keep your brain in good condition

    By Steffanie Zazulak

    Learning and understanding a new language is one of the most challenging things that your brain can do. But as well as the advantage of acquiring another language, it appears that the effort of giving your brain a good workout today by being bilingual could keep it in better condition in later life.

    Research led by Dr. Daniela Perani, a professor of psychology at in Milan, found that people who speak two or more languages seem to weather the ravages of Alzheimer’s disease better compared to people who have only mastered one language. Alzheimer’s is a progressive mental deterioration that can begin in middle or old age due to generalized brain degeneration.

    The study involved 85 people with Alzheimer’s – half of whom spoke both German and Italian and half who spoke only one language. The researchers found that bilingual patients had greater connectivity in key brain areas. This was especially in the part of the brain that governs “executive control” – a set of necessary behavioral cognitive processes that include problem-solving, working memory, reasoning and attentional control. The study also noted that the bilingual Alzheimer’s patients showed less severe symptoms of the disease.

    The study concluded: “Our findings suggest that the effects of speaking two languages are more powerful than both age and education in providing a protection against cognitive decline.”

    Bilingualism and the brain

    Although Alzheimer’s disease is currently incurable, the study supports a popular theory that people who have higher levels of education function longer with little manifestation of the illness. Part of the reason why bilingual brains may be better at resisting Alzheimer’s could be due to a lifetime of switching between languages daily.

    Learning and speaking more than one language changes how the brain carries out tasks that require focus and concentration on a certain piece of information without being distracted. It can also increase the density of white matter (connections) in the brain, meaning that there are more connections between brain parts, thus making this part of the brain more resistant to degeneration.

    This is supported by a study conducted by a team led by Professor Ana Inés Ansaldo at the , which suggests that bilingual people have more robust and more efficient brains compared to those who only speak one language. This is one of the reasons why a bilingual brain can be a buffer against aging and dementia.

    They recruited elderly people, half of whom spoke only one language and the other half who had learned a second language between the ages of 11 and 18. All performed equally well on a task that involved focusing on an object's color while ignoring its position, but brain scans revealed a big difference in how they processed the task.

    “While bilinguals were recruiting very specific brain areas and a small number of areas to perform the task, monolinguals were recruiting a much larger number of areas that were consuming much more resources. And the networks they were using were very, very complex,” says Professor Ansaldo. “That led us to think that the bilingual brain was more efficient in terms of the amount of resources that bilingual people require to do complex tasks as opposed to the monolingual brain.”

    The study concludes that bilingualism shapes the brain in a different way or how people approach complex tasks. It could be because bilinguals must inhibit the language they are not using to focus on the one that they are using.

    5 of the strangest English phrases explained

    By Steffanie Zazulak

    Here, we look at what some of the strangest English phrases mean – and reveal their origins…

    Bite the bullet

    Biting a bullet? What a strange thing to do! This phrase means you’re going to force yourself to do something unpleasant or deal with a difficult situation. Historically, it derives from the 19th century when a patient or soldier would clench a bullet between their teeth to cope with the extreme pain of surgery without anesthetic. A similar phrase with a similar meaning, “chew a bullet”, dates to the late 18th century.

    Use it: “I don’t really want to exercise today, but I’ll bite the bullet and go for a run.”

    Pigs might fly

    We all know that pigs can’t fly, so people use this expression to describe something that is almost certain never to happen. It is said that this phrase has been in use since the 1600s, but why pigs? An early version of the succinct “pigs might fly” was “pigs fly with their tails forward”, which is first found in a list of proverbs in the 1616 edition of John Withals’s English-Latin dictionary, A Shorte Dictionarie for Yonge Begynners: “Pigs fly in the ayre with their tayles forward.” Other creatures have been previously cited in similar phrases – “snails may fly”, “cows might fly”, etc, but it is pigs that have stood the test of time as the favored image of an animal that is particularly unsuited to flight! This phrase is also often used as a sarcastic response to mock someone’s credulity.

    Use it: “I might clean my bedroom tomorrow.” – “Yes, and pigs might fly.”

    Bob’s your uncle

    Even if you don’t have an uncle called Bob, you might still hear this idiom! Its origin comes from when Arthur Balfour was unexpectedly promoted to Chief Secretary for Ireland by the Prime Minister of Britain, Lord Salisbury, in 1900. Salisbury was Arthur Balfour’s uncle (possibly his reason for getting the job!) – and his first name was Robert. This phrase is used when something is accomplished or successful – an alternative to “…and that’s that”.

    Use it: “You’re looking for the station? Take a left, then the first right and Bob’s your uncle – you’re there!”

    Dead ringer

    This phrase commonly refers to something that seems to be a copy of something – mainly if someone looks like another person. The often-repeated story about the origin of this phrase is that many years ago, people were sometimes buried alive because they were presumed dead – when actually they were still alive. To prevent deaths by premature burial, a piece of string would supposedly be tied to the finger of someone being buried – and the other end would be attached to a bell above ground. If the person woke up, they would ring the bell – and the “dead” ringer would emerge looking exactly like someone buried only a few hours ago! Other stories point to the practice of replacing slower horses with faster horses – “ringers”. In this case, “dead” means “exact”.

    Use it: “That guy over there is a dead ringer for my ex-boyfriend.”

    Off the back of a lorry

    This is a way of saying that something was acquired that is probably stolen, or someone is selling something that’s stolen or illegitimate. It can also be used humorously to emphasize that something you bought was so cheap that it must have been stolen! “Lorry” is the British version – in the US, things fall off the back of “trucks”. An early printed version of this saying came surprisingly late in The Times in 1968. However, there are many anecdotal reports of the phrase in the UK from much earlier than that, and it is likely to date back to at least World War II. It’s just the sort of language that those who peddled illegal goods during and after WWII would have used.

    Use it: “I can’t believe these shoes were so cheap – they must have fallen off the back of a lorry.”
