Word roots that travel
One root → a family of words → cognate bridges across Romance languages. The books rendered interactive in the Root-Family Explorer.
Why lists fail at the plateau
Beginners can memorize. Intermediate learners drown in near-synonyms and opaque advanced vocabulary. Roots give a retrieval structure: when you meet inspeccionar, you already own espectáculo, respeto, and the English bridge inspect.
The CEFR ladder
Each pillar language gets three level paths mapped to the book series:
- A1–A2 starter — first roots, high-frequency families, survival grammar.
- B1–B2 plateau — the marketing wedge: denser roots, false friends, speaking practice.
- C1–C2 mastery — register, nuance, and native media with method still in hand.
Routines, not hacks-as-gimmicks
Daily root-of-the-day, short Explorer sessions, and immersion from the directory (slow news → broadcasters → newspapers). Free tools stay complete; paid packs go deeper — never crippled-free.
