Writing: Advanced Argumentation & Persuasion C1 - Lesson 6: Formal vs. Informal Register: A Masterclass

Register

ទម្រង់ភាសាផ្លូវការ និងក្រៅផ្លូវការ

Register is how we adapt our language based on the audience and purpose. Academic writing demands strict formality.

Register គឺជាការផ្លាស់ប្តូរទម្រង់ភាសាទៅតាមកាលៈទេសៈ និងអ្នកស្តាប់។ ភាសាដែលប្រើសរសេរផ្ញើឲ្យមេ និងមិត្តភក្តិ គឺខុសគ្នាស្រឡះ។

Hi Panha! Generally, academic writing demands objectivity, so we avoid personal pronouns (I/We/You). Instead of saying "I think this is true," use the passive voice or third-person: "It can be argued that this is true," or "Evidence suggests this is true." 🎓✍️
