The full training programme — row-by-row quizzes, section quizzes with an 80% pass threshold, and progress tracking — is available on Polyglot™, the master platform covering all 22 languages simultaneously.
For Celtic-focused learners: Once on Polyglot™, use the Column Order modal to bring Welsh, Old Welsh, Revitalised Cumbric, Cornish, Breton, Irish Gaelic, and Scottish Gaelic to the front. The triangulation method — seeing all seven Celtic languages side by side — makes patterns immediately visible.
Pronunciation: Use ChatGPT in voice mode or Google Gemini alongside each study session. Read each row aloud and ask for pronunciation feedback — this is an integral part of the recommended learning process.
Rows per Day: Use the 📅 button on Polyglot™ to set your daily target. One row per day is a sustainable pace; at this rate every row you study has already been reviewed by the Penrith Beacon Communications | PBC team.
