3 errores típicos con idioms
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. Traducir idiom literal sin contexto cultural
"Está lloviendo a cántaros" ≠ "It's raining buckets". Es "It's raining cats and dogs". Memorizar conjunto.
3. Sobre-usar idioms intentando 'sonar nativo'
1-2 idioms por conversación es natural. 5+ suena forzado y robótico.
