How do polyglots learn faster than most people ? This Savoir en bref mini book brings together scientific findings from 2024 and 2025 and practical advice from leading linguists to answer that question. You will discover how hyperpolyglots' brains optimise their activity, why plurilingualism protects against ageing and Alzheimer's disease, and how spaced repetition, memory palaces and cultural immersion transform learning.

The text also highlights the role of AI and gamification while reminding us that human guidance remains essential. It denounces inequalities in access to language education and shows the positive impact of bilingualism on children, autistic individuals and seniors.

By combining recent studies, expert testimony and a detailed action plan, this Five Minutes title in the Savoir en bref series offers a clear, motivating and rapid approach. Whether you want to learn English, Mandarin or strengthen your multilingualism, you will leave with proven methods and an irresistible urge to start.
