3 errores típicos con idioms

  1. 1. Usar idioms en contextos formales

    Cover letter o reporte ejecutivo NO lleva "low-hanging fruit". Usar idioms en oral informal o semi-formal solamente.

  2. 2. Traducir idiom literal sin contexto cultural

    "Está lloviendo a cántaros" ≠ "It's raining buckets". Es "It's raining cats and dogs". Memorizar conjunto.

  3. 3. Sobre-usar idioms intentando 'sonar nativo'

    1-2 idioms por conversación es natural. 5+ suena forzado y robótico.
