Las palabras que cada lección pone en juego en sus ejercicios, unidad por unidad,
y en qué unidad se estrenó cada una. Progresión 6a981e2a…ba52, borrador en inglés.
Cada una se presenta como nueva en dos o más unidades. La regla es que la unidad que va después en la sección es la que cede: ahí la palabra debería aparecer como repaso con contexto, no como estreno. El badge de borde discontinuo marca una reaparición que solo toca Match Pairs —contexto, no enseñanza—; el de borde continuo, una que sí la vuelve a enseñar.

Leído del servidor el 8 de septiembre de 2026: 84 lecciones, 761 ejercicios del banco. Cuenta como palabra de la lección el primaryItem y los items de cada ejercicio; los señuelos no cuentan. Build y Listening no aportan palabra: trabajan la frase o el clip. Las fichas en cursiva son phrase items. El repaso interno —palabra ya vista en una lección anterior de la misma unidad— está oculto por defecto; pasa el ratón por cualquier ficha para ver en qué ejercicios sale.
