Kirkus Reviews

“Marian, a professor of communication sciences and disorders at Northwestern University, makes a convincing case for multilingualism in her illuminating debut…Marian’s extensive research and thoughtful analysis lend this entry weight, and the lay reader-friendly prose makes it all go down smoothly. Curious monolinguals will be inspired to expand their linguistic horizons.” 

Publishers Weekly

“Packed with evidence-backed insights about the power of language. And the "codes we use to think, speak, and live" - reflected  in the subtitle of the US edition - makes for an endlessly fascinating topic.

New Scientist

Professor Marian was one of the pioneers in the field of psycholinguistics and has been studying multilingual brains since the 1990s. In her new book “The Power of Language: Multilingualism, Self and Society” she explores the body of research surrounding multilingualism – including some of her own – explaining it in simple, understandable terms.


A fascinating, humorous, and highly readable tour through decades of research on the psychology of language.

Fast Company

A great new book by the cognitive scientist Viorica Marian called The Power of Language explores a number of influences of speaking multiple languages on the way people engage, think, and act.

Psychology Today

An enjoyable and stimulating account of the blessings of bilingualism.

The Linguist, professional journal of the Chartered Institute of Linguists

The Power of Language, written by Viorica Marian, a psycholinguistics researcher, helped me understand ... communication that changed my brain, opening me up to new knowledge and new experiences.

Harvard Business Review

Bilingual readers have much to gain.

Financial Times

This book is very enjoyable to read … the language of the register is accessible, and the numerous personal examples offered by the author give the book a very friendly tone and make the content easily understood. … valuable information for ELT educators on a personal and professional level.

Morning Star

“Sparkles with insight. After reading this book, you will see and hear words differently—and feel a deeper appreciation for the sheer majesty of the human mind. (Bonus: It will also make you want to learn Swedish, Spanish, or Swahili!)  Viorica Marian takes her place alongside Steven Pinker and George Lakoff as the author of an essential work about the science of language.”

Daniel H. Pink, #1 New York Times bestselling Author of Drive, When, and The Power of Regret

Whether or not you have reflected on language, whether or not you speak or think in several languages, you will learn a lot from this well-researched and well written book.” 

Howard Gardner, Professor, Harvard Graduate School of Education, Author of the seminal bestseller Frames of Mind: The Theory of Multiple Intelligences

There exist countless books on language, each one a variant, it sometimes appears, of the ones that preceded it. But Viorica Marian has done the seemingly impossible – given us a uniquely original, fresh, and powerful perspective that promises to shape the scientific study of language and mind well into the future. Her focus is not so much on how the mind does language as on what language does for the mind and its user, and crucially, on what the consequences are, for individuals and entire societies, of having more than one language in that mind. Specialist and non-specialist readers alike will be captivated. As a seasoned psycholinguist, I am inspired.” 

Gerry Altmann, Former Editor of Cognition ­– the International Journal of Cognitive Science, and award-winning Author of The Ascent of Babel

A highly engaging and personal journey into the superpower you didn’t know you had: the ability to learn multiple languages. With flair and witty anecdotes, Viorica Marian decodes intriguing scientific evidence showing how multilingualism can make you smarter, increase your creativity, make you more attractive to others, and even protect you against dementia.” 

Morten H. Christiansen, Author of The Language Game

If you speak only one language, you might be tempted to assume there's only one way to see the world. Many Americans took a couple years of a second language in high school but went no further. Meanwhile, the American poet Ferlinghetti wrote: Pity the nation that knows no other language than its own. In The Power of Language, Dr. Viorica Marian – an internationally renown expert in bilingualism research – beautifully shows all the ways that learning a second language can do so much more than simply add another way of talking; it can fortify your brain to make you sharper, wiser, more creative, and more open-minded. And she provides the scholarly receipts for her evidence in a comprehensive Notes section. With clear prose, insightful analogies, and a sly sense of humor, Marian reports masterfully on the science of bilingualism to reveal that one of the most effective ways for any monolingual to expand and improve their mind is to learn a second language.” 

Michael J. Spivey, Professor of Cognitive Science, University of California, Author of Who You Are and The Continuity of Mind

In this easy-to-read and informative book, Professor Viorica Marian marshals her extensive research experience, broad knowledge of science, and a personal and engaging style in telling the story of the one arguably most human cognitive faculty: language. Among other things, this book explains how the mastery of language — or, even better, of several languages — helps us think better, live better for longer, and be better to each other. Read it, and you’ll be better for it!” 

Shimon Edelman, Professor of Psychology, Cornell University, Author of  Computing the Mind and The Consciousness Revolutions

The Power of Language is OUTSTANDING. It will change the way people think about the mind and its plasticity, and it will make everyone want to learn a second, third, or fourth language.           

Rachel Jamison Webster, Northwestern University Professor of Creative Writing, Author of Benjamin Banneker and Us: Eleven Generations of an American Family

An absorbing account of how language wires the brain.

Marian, director of Northwestern’s Bilingualism and Psycholinguistics Research Lab, is an expert on the relationship between language and the human brain. In this eye-opening account, she describes the results of decades of research in accessible, engaging prose. Some of the most intriguing conclusions are related to bilingualism and multilingualism, which have been shown to delay Alzheimer’s, increase the brain’s gray matter, and positively impact social cognition in children. Bilingual babies can better distinguish between musical notes, suggesting that the powerful effects of multilingualism on the brain are present even in nonverbal areas. Furthermore, languages bring cultural connotations, memories, and connections. “Learning another language doesn’t just give you different words or more words,” writes the author. “It rewires your brain and transforms it, creating a denser tapestry of connectivity.” This radical transformation means that multilinguals communicate and even vote differently depending on which language they are using, allowing them to become a somewhat different version of themselves. Memories and emotions differ across linguistic and cultural experience and have clear manifestations in bilinguals. For example, people tend to be more emotional when speaking in their native language. On the individual level, being bilingual improves creativity, executive function, and aging. Socially, politically, and psychologically, understanding how languages affect the brain is just as essential, especially in the U.S., where more than 350 languages and dialects are spoken. “Engaging with a variety of languages,” writes the author, “gives us crucial abilities that the human race will need to heal burgeoning social discord and to formulate solutions to looming global problems.” Thoroughly researched and carried by Marian’s own experiences as a multilingual who speaks fluent Romanian, Russian, and English, the narrative is both fascinating and fluid.

Full of delightful insights, this book is thoroughly researched and compulsively readable.”
