This is the category that includes all those words that, due to one or two letters of difference, resemble others (but I assure you, it's possible to distinguish their pronunciation). Just confuse one word with another, and disaster is guaranteed!

Some of the most ridiculous examples include:

• Miss Nelly, described as irresistible, becomes definitely resistible (Resistibile/Resistibile)
• The glorified detective becomes the nonsensical detective (Incensato/Insensato)
• The smile becomes her rice (Il sorriso/Il suo riso)
• Lupin "The sign" (Arsenio/Il segno), but also "At the saint Lupin" (Al san/Arsenio)
• Rose (verb) becomes Absurd (Assurse/Assurde)
• Lupin's unlimited powers become very limited (Illimitati/Limitati)
• Worrying that Lupin is not among the remaining people on the steamboat becomes worrying that he's unhappy (Tra esse/Triste)
  
• Lupin gets compared to a magician, but instead he's only an average human (Un mago/Umano)
