Self-Study Tips
- Read Tech News: Subscribe to Japanese tech news outlets like ITmedia or Nikkei CrossTech. N1 learners should focus on the editorial sections to see how these abstract nouns are used in context.
- Contextual Flashcards: Don't just memorize the word "脆弱性" (vulnerability). Memorize the collocation "脆弱性を突く" (to exploit a vulnerability) to understand how the word functions in a sentence.
- Summarization: After reading a tech article, try to summarize the main point in three sentences using at least five of the vocabulary words from the table above.
- Active Usage: If you work in a tech-related field, try to use these terms in your next Japanese email or meeting to solidify your professional vocabulary.
