6. Common Mistakes and Tips

Error Analysis

1. Confusing Hearsay and Appearance Forms
   • Incorrect: 美味しいだそうだ。(Adding "だ" after an い-adjective for appearance)
   • Correct: 美味しそうだ。(Omit "だ" with い-adjectives in appearance form)
2. Using the Wrong Adjective Form
   • Incorrect: 静かいそうだ。(Adding "い" to a な-adjective)
   • Correct: 静かそうだ。(Do not add "い" to な-adjectives)

Learning Strategies

• Remember the Verb Forms:
  • For hearsay, use the plain form.
  • For appearance, use the stem form (remove ます from verbs, remove い from い-adjectives).
• Visual Clues for Appearance:
  • If you're making a guess based on what you see, it's likely the appearance form.
• Hearsay Indicators:
  • If you're relaying information from someone else, use the hearsay form.
