More resources on Language Acquisition
Luca Lampariello
Luca Lampariello speaks 14+ languages and has been publishing methodology videos since 2008, making his channel one of the most thoughtful long-form archives on adult language learning. He is especially known for his work on bidirectional translation, deliberate input selection, and the psychology of long-term study. Less viral than other polyglot channels, more substantive — closer to a personal masterclass than a content feed.
StoryLearning by Olly Richards
StoryLearning is Olly Richards' methodology hub built around the premise that languages are best acquired through compelling narrative input rather than drills. The site hosts his blog, podcast, and free guides on story-based learning, plus method articles drawn from his experience speaking eight languages. It is one of the few methodology resources written by someone who built a career on the specific technique they teach.
LingQ
LingQ is a reading-and-listening platform built around comprehensible input: import any text or transcript, look up unknown words inline, and track them as they move from new to known across thousands of repetitions. Co-founded by polyglot Steve Kaufmann, it operationalises the input hypothesis better than any other tool by making 'reading at your level' the central daily habit. A free tier supports a meaningful amount of practice before any paywall kicks in.
Steve Kaufmann — lingosteve
Steve Kaufmann, co-founder of LingQ and speaker of 20+ languages, runs one of the most enduring polyglot YouTube channels with frank, opinionated videos on input-based learning, plateaus, and adult acquisition. Drawing on decades of self-experimentation across language families, his content is less performance and more methodology — useful for anyone choosing how to spend their study hours. The signal-to-noise ratio is unusually high for a creator who posts this consistently.
The secrets of learning a new language (TED talk)
Lýdia Machová is a Slovak polyglot and translator who, in this widely viewed TED talk, distills the four principles she observed across successful polyglots: enjoyable methods, effective techniques, well-designed systems, and patience. It is a fast, clear-headed overview that reframes language learning as a behavioural problem rather than a talent problem, making it an ideal first watch before committing to a method.
