Lesson Summary & Review

Let's review the key concepts covered in the interactive module above to ensure you are deploying C1 vocabulary effectively.

Core C1 Vocabulary

• Meticulous: Showing great attention to detail; very careful and precise.
• Charismatic: Exercising a compelling charm that inspires devotion in others.
• Ambiguous: Open to more than one interpretation; unclear.
• Inevitable: Certain to happen; unavoidable.
• Absurd: Wildly unreasonable, illogical, or inappropriate.
• Profound: Very great or intense; having or showing great knowledge or insight.

The Thesaurus Trap

At the C1 level, your goal is semantic precision, not just sounding smart. Using highly sophisticated words in basic, everyday contexts (like calling a sandwich "profound") sounds unnatural and confusing. Always match the register of your vocabulary to the complexity of the topic you are discussing.
