This Is Why It's So Hard to Learn a Second Language as an Adult

If learning a foreign language seems to get harder and harder with age, it isn't just your imagination. A new study by Boston-based researchers, including experimental psychologist Steven Pinker, finds that language-learning ability starts to decline after age 18, the BBC reports.

And if you want to sound like a native speaker, your chances are better if you started learning before the ripe old age of 10. Using the results of an online grammar test that was circulated on Facebook, researchers determined that children have the best capacity for learning complex grammar rules, while those of us who started learning a language in adulthood "are often saddled with an accent and conspicuous grammatical errors." Their findings were published in the journal Cognition, and they're in the process of developing similar tests for Spanish and Mandarin speakers.

The online test was taken by nearly 670,000 Facebook users of all ages from around the world—one of the largest linguistic studies ever conducted, according to Scientific American. Test takers were asked their age, how long they had been learning English, and the countries they've lived in for at least six months. The study found that people who learned a language by immersion were more fluent than those who learned in a classroom. Based on these test results and demographics, researchers developed models to predict how long it takes to achieve fluency in a language.

Researchers aren't sure what causes the drastic decline after age 18, but they believe it has something to do with the fact that the brain becomes less adaptable in adulthood.

However, that's no reason to sell your Rosetta Stone software just yet. Researchers say dedicated language learners can still become proficient—even fluent—well into adulthood. A study from 2014 revealed that learning a new language as an adult can help slow brain decline, and other studies point to the benefits of being bilingual, including a later onset of dementia. But the Boston researchers also found that it takes 30 years to fully master a language, so it's best to get started right away.

The Surprising Origins Behind 9 Modern Slang Expressions

Slang evolves so quickly these days—especially on social media—that it can be hard to recall how we first learned a term, much less where it actually came from. This list will help you figure out whether you should be thanking Erykah Badu, LL Cool J, or an academic journal for some of the expressions you love to throw around in conversation and online.

  1. FOMO

A marketing strategist named Dan Herman claims to have identified the FOMO (Fear of Missing Out) phenomenon and published the first academic paper about it in The Journal Of Brand Management in 2000. Yet the credit for the popular usage of FOMO often goes to venture capitalist and author Patrick J. McGinnis, who used the term in 2004 in an op-ed for Harvard Business School’s magazine The Harbus to describe the frenetic social lives of his grad school cohort. (One acronym from the op-ed that McGinnis deserves complete credit for: FOBO—Fear of a Better Option.)

  1. Bye, Felisha!

A diss by any other name might still sting as sweet, but there's something satisfying about ending a conversation with "Bye, Felisha!" (Though it’s often mistakenly written as Felicia.) The phrase comes from the 1995 stoner comedy Friday, co-written by and starring Ice Cube as Craig, a young man in South Central Los Angeles just trying to get to the weekend. When the mooching bit character Felisha (played by Angela Means Kaaya) asks Craig’s friend Smokey (Chris Tucker) if she can borrow his car and then a joint, Craig mutters "Bye, Felisha." And now everyone says it, though usually as an exclamation.

  1. Lit

In the last few years, lit has been literally everywhere—in popular music, speech, memes, and a series of articles about what it actually means. People have been using the word to mean “intoxicated” since at least 1918, when John McGavock Grider, an American pilot who served in England's Royal Flying Corps during World War I, used it in his book War Birds: Diary Of An Unknown Aviator. In recent years, however, hip hop has brought the word back to describe a general excitement that can be achieved with or without substances.

  1. Woke

Neo-soul singer Erykah Badu has been credited with bringing woke into popular usage with the 2008 song “Master Teacher,” which was a collaboration with the musician Georgia Anne Muldrow. But using the word to mean “aware in a political or cultural sense” dates back to 1962, when novelist William Melvin Kelley tackled appropriation of black culture in a New York Times article entitled “If You’re Woke You Dig It.” The Oxford English Dictionary finally “woke” up (sorry) and included this timely definition of the word in 2017.

  1. Humblebrag

Humankind has probably been humblebragging since that one Neanderthal complained about how bloated he felt after eating too many woolly mammoths over the weekend. Credit for the term, however, goes to Harris Wittels, the late comedian and writer best known for Parks and Recreation. He coined humblebrag in 2010, explaining the concept through retweeted examples from celebrities on the @Humblebrag Twitter account before publishing Humblebrag: The Art of False Modesty in 2012.

  1. On Fleek

This phrase was first used in 2014 by a Vine user named Peaches Monroee to describe perfectly groomed eyebrows. But fleek is defined in the annals of Urban Dictionary as early as 2003 as “smooth, nice, sweet” and 2009 as “awesome.” It quickly evolved to encompass anything that’s flawlessly on point, until adults started awkwardly using it and younger, hipper English speakers moved on to the next vernacular phrase we’re probably not cool enough to have heard yet.

  1. First World Problem

A cousin of humblebrag, this phrase is a helpful reminder to count our blessings and stop complaining about trivial setbacks, like a delayed flight or, if you're really fortunate, slow Wi-Fi on the yacht. It may feel like a relatively new addition to the vernacular, but the phrase "First world problem" has been around since 1979, when an academic named Geoffrey K. Payne used it in an article in the journal Built Environment (although Payne was talking about legitimate First World Problems, notably housing). The more ironic usage developed in the 1990s, perhaps helped along by the Matthew Good Band song "Omissions of the Omen," which included the term in the lyrics. But it didn't go mainstream until it became a self-deprecating internet meme around 2005.

  1. Yas/Yass/Yaass

Everyone’s favorite new affirmative was added to the Oxford Dictionary in 2017 and defined as “expressing great pleasure or excitement.” Many first heard it on Broad City, which debuted in 2014. But according to "Reply All," we owe its current popular American usage to the LGBTQ black and Latino ball scene of the 1980s, where attendees hollered “Yas!” at the sight of fiercely strutting drag queens. Ball culture was fertile linguistic ground, by the way: The subculture also gave us voguing (which inspired Madonna), fierce, throwing shade, and more. Call it the Kween’s English.

  1. G.O.A.T.

James Todd Smith, better known as the rapper LL Cool J, clearly loves wordplay: The letters in his stage name stand for Ladies Love Cool James. So it’s no surprise that he brought the acronym G.O.A.T. (Greatest Of All Time, pronounced like the name of the animal) into popular usage with the 2000 hip hop album of the same name. But many trace the use of G.O.A.T as an initialism to boxer and fellow wordsmith Muhammad Ali, who frequently referred to himself as "the greatest" and occasionally "the greatest of all time." In 1992, Ali’s wife Lonnie even incorporated Greatest of All Time, Inc. (G.O.A.T. Inc.) to consolidate and license her husband’s intellectual properties.
