✕Common Mistakes

  • Melhorar a eficiência do sistema.

    Using the infinitive ‘melhorar’ makes the sentence sound like a title or a suggestion, not a statement or command.

  • Melhora da eficiência do sistema.

    ‘Eficiência’ is feminine, so the correct article is ‘a’, not ‘da’. ‘Da’ would be used before a masculine noun.

  • Melhora do eficiência do sistema.

    ‘Eficiência’ is feminine; the preposition‑article contraction should be ‘da’, not ‘do’.

↔Alternatives

  • Aumenta a eficiência do sistema.

    Increases the efficiency of the system.

  • Eleva a eficiência do sistema.

    Elevates the efficiency of the system.

Cultural Tip

In Brazilian Portuguese, ‘melhorar’ is the most common verb for ‘to improve’ in business contexts. Avoid using ‘aumentar’ when you mean a qualitative boost rather than a quantitative rise. The phrase is neutral in register, suitable for meetings, reports, and presentations.
