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.

    Three ways to learn new English words

    By Vaughan Jones

    It’s more important for teachers to help students find ways to practice their English outside the classroom. The more efficient students become at autonomous learning, the better they’ll be able to overcome interruptions and make up for lost time.

    It will be even more challenging if you're a self-learner as you do not have a teacher looking over you and steering your learning. But it’s helpful to learn from the teaching world and pick up teacher tips that you can apply to your own studies and techniques.

    Why are learning new words so challenging?

    Students learning new words in English generally progress steadily up until the pre-intermediate and intermediate levels. But after that, they start to struggle.

    This is because there’s a big difference between the volume of the vocabulary that intermediate students and upper-intermediate students need to know.

    • Intermediate (B1/B2 level) students need to know about 2,500 words
    • upper-intermediate (B2/C1 level) students need to know about 7,500-9,000 words.

    That’s a big jump in numbers. But the real challenge is that those 5,000+ new words are not very frequent. Consequently, students don’t encounter them very often, making it difficult to recall them and leap from one level to the next.

    While there’s no simple answer to this problem, there are ways to help students overcome it. The following framework can be a big help in any classroom:

    1. Focus on the most important words:Always teach appropriate words for the levels your students are currently at.
    2. Provide memorable first encounters:You never get a second chance to make a first impression. So, ensure your student's first encounter with a new word is as memorable as possible.
    3. Teach effective word-learning strategies:Provide your students with valuable tools, tactics and resources so that they can learn new words outside the classroom, too.
    4. Organize repeat encounters:Vocabulary works on a “use it or lose it” basis, so ensure your students encounter the vocabulary you want them to learn repeatedly.

    How to teach effective word-learning strategies

    There are three steps to teach students how to learn new words effectively:

    1. Help learners maximize their exposure to English and find opportunities to use English outside the classroom

    Thanks to the internet and technology, there are many ways that students can engage with the English language outside the classroom.

    However, simple exposure to a new language is not enough – it takes much longer and is less effective than active learning. When students do something with the language they’re exposed to; it is far more memorable.

    That’s why it’s crucial for teachers to help their students seek out English in their own time and use the language, turning passive exposure into active learning.

    • Encourage students to read, listen and view things that they’re interested in or passionate about in English. For example, introduce them to new blogs, podcasts, YouTube videos, or TV series that fit their interests – since personalization leads to more effective learning.
    • Help students find ways to use English in different ways. For example, they can start a learning diary, make to-do lists in English, write social media posts, and create word cards to practice their writing. For speaking, they can record voice memos or video stories, take part in Zoom discussions, or participate in speaking projects and live classes.

    2. Provide ways for students to discover the meaning of new words

    It’s crucial to help students improve their guesswork. Instead of asking online translators to translate every time they encounter a new word, they should be able to guess the meaning of new vocabulary differently.

    • One approach is to look at the morphology of words and consider word families. For example, you can ask your students to brainstorm words with a common root. Or, you can have them identify and practice common suffixes.
    • Explore “true friends” or words that are similar in English and your student's native language.
    • Help your students figure out how to guess the meaning of a word from the context. To do this, you must ensure that your students don’t just hear or read new words but also put them into use.

    One way to get students to learn and retain vocabulary is to get them to create word cards:

    • Ask students to collect ten new words that they’re exposed to throughout the week and bring them to class, like a “show and tell” for words.
    • Then have a debate about how useful each of those words is.

    This helps to connect learning inside and outside the classroom, and it’s fun!

    3. Provide students with strategies to consolidate their knowledge of new words

    Finally, teachers should give students ideas on how to memorize words outside the classroom. You can have your students produce word cards and use a Word Store booklet to practice tasks like matching words with images or definitions.

    Lastly, it’s important to teach students memory tricks or mnemonics so they can retain the new words they encounter.

    How do English phrases travel across countries?

    By David Crystal

    All living languages change. It’s a fact of life that some people find uncomfortable, but that no one can prevent. The only languages that don’t change are dead ones.

    How does change happen? The chief way is through mutual influence, when languages – which means people – come into contact with each other. An immediate effect is that words and phrases begin to be exchanged.

    Origins of English

    The history of English shows this taking place from the very beginning. When the Germanic tribes first arrived in Britain, bringing with them the dialects that would become English, their vocabulary already contained words and phrases borrowed from Latin, a consequence of the interaction with the soldiers of the Roman Empire.

    Today we think of such words as 'butter', 'cup', 'kitchen', 'mile', and 'street' as true English words, but they are all Latin in origin ('butyrum', 'cuppa', 'coquina', 'mille', 'strata'), taken into Germanic while the tribes were still on the European mainland.

    The process continued over the centuries. An everyday word like 'take' reminds us of the Viking invasions, for this came from Old Norse 'tacan'. So did 'knife' (from 'knifr'). Even basic grammatical items were affected: 'they', 'them', and 'their' are all from Old Norse.

    When the French arrived, in the eleventh century, the borrowing became a flood, with thousands of French words expanding the vocabulary to an unprecedented size, in such domains as law, religion, politics, food, and the arts – 'duke', 'abbot', 'war', 'peace', 'pork' and 'beauty'. During the Renaissance, Latin added tens of thousands more.

    In all cases, the words traveled because cultural contact – in its broadest sense – made them do so.

    The history of contact

    This history of contact is one of the reasons that English has so many near-synonyms: we can 'ask' (from Old English), 'question' (from French), and 'interrogate' (from Latin). We can talk about a 'fire', 'flame', and 'conflagration'; 'kingly', 'royal', and 'regal'. But although French and Latin are the dominant voices, they are put in the shade by the accumulated impact of the many languages that English has since encountered as its speakers moved around the globe, especially in the days of the British Empire.

    Today, a search through the files of any major dictionary shows the presence of hundreds of languages, from 'aardvark' (Afrikaans) to 'zygote' (Greek).

    It’s been estimated that around 80 percent of present-day English vocabulary comes from languages other than the original Anglo-Saxon Germanic. English seems to always be a vacuum cleaner of a language, sucking in words from whichever culture it was in contact with. The process continues. In recent years, dictionary writers have been considering such new borrowings of words from other languages.

    But not everything in language change is due to borrowing. When we look at recent lists of updates in the dictionary world, we find hundreds of phrasal expressions, such as 'solar farm', 'travel card', 'skill set', 'cold caller', 'air punch', and 'set menu'.

    Blends of existing words form an increasingly large component of modern vocabulary, such as 'glamping' (glamorous + camping) and 'Pokemon' (pocket + monster), as do internet abbreviations, such as 'GTG' (got to go) and 'BRB' (be right back).

    And it’s here that we see the most noticeable phenomenon of the last few decades: the impact of English on other languages. The traveling is now going in both directions.

    Over a decade ago, Manfred Görlach published his Dictionary of European Anglicisms, showing English to be "the world’s biggest lexical exporter”. The book lists hundreds of words and phrases that have entered the languages of Europe. A small selection from letter 'A' shows 'ace' (from tennis), 'aerobics', 'aftershave', and 'aqualung', as well as phrases such as 'acid house' and 'air bag'.

    The factors are exactly the same as those that brought foreign words into English in the first place, such as business, culture, medicine, sport, the arts, popular music, science and technology. The difference is that these expressions come from all over the English-speaking world, with American English the primary supplier, thanks chiefly to its presence in the media.

    The impact of media

    It is the media that provides the main answer to the question “How?”. In the old days, face-to-face contact caused expressions to be shared, and it would take time for words to travel – a generation before a word would become widely used. Today, the use of English in film, television, and especially the internet allows 'word travel' to take place at a faster rate than ever before.

    A new word or phrase invented today can be around the globe by tomorrow, and if it appeals it will spread on social media and become part of daily use in no time at all. Even an everyday phrase can receive a new lease of life in this way.

    Many countries try to resist the borrowing process, thinking that an uncontrolled influx of English expressions will destroy their language.

    The evidence from the history of English shows that this does not happen. Because of its global spread, English has borrowed more words than any other language – and has this caused its destruction? On the contrary, in terms of numbers of users, English is the most successful language the world has ever seen.

    Borrowing does change the character of a language, and this too is something that causes concern. But again, I ask: is this inevitably a bad thing? Shakespeare would have been unable to write his characters in such an effective way without all those borrowings from French and Latin.

    Much of his linguistic playfulness and creativity relies on how everyday words are contrasted with their scholarly or aristocratic counterparts. In Love’s Labour’s Lost, Don Armado gives Costard a coin as a tip, calling it a "remuneration".

    Costard has no idea what the word means, but when he looks at his coin he realizes he’s been given a tiny amount. “Oh, that’s the Latin word for three farthings”, he reflects. “I will never buy and sell out of this word”. It always gets a laugh from an audience.

    Today's challenges

    Keeping up-to-date with language change is probably the greatest challenge facing foreign language learners because there is so much of it.

    Textbooks and teachers face a daily risk of falling behind the times. But the risk can be reduced if we build an awareness of change into the way we present a language. And understanding the natural processes that underlie linguistic change is the essential first step.
