Common Mistakes

  • La filtro del condizionatore è sporco.

    ‘Filtro’ is masculine, so the article must be ‘il’, not ‘la’.

  • Il filtro del condizionatore è sporcato.

    ‘Sporcato’ is the past participle; the correct adjective for a current state is ‘sporco’.

  • Il filtro del condizionatore d'aria è sporco.

    Both forms are acceptable, but avoid mixing the article: ‘del condizionatore d'aria’ is redundant; choose one: ‘del condizionatore’ or ‘dell'aria’.
