Formal vs. Informal

ការប្រើប្រាស់ភាសាផ្លូវការ និងក្រៅផ្លូវការ

A register is the level of formality in language. Choosing the right register is like choosing the right clothes for an occasion!

ការជ្រើសរើសពាក្យពេចន៍ (Register) ប្រៀបដូចជាការជ្រើសរើសសម្លៀកបំពាក់អញ្ចឹង។ យើងមិនពាក់អាវធំទៅមាត់សមុទ្រទេ! ភាសាអង់គ្លេសក៏ដូចគ្នា។

Teacher, is it bad if I use formal words when I talk to my friends? I want to sound smart!

Hi Panha! Yes, it can actually be a mistake! In English, sounding "smart" means knowing the RIGHT register. If you use highly formal language at a coffee shop (e.g., "I shall commence consuming my beverage"), you won't sound smart—you will sound like a robot! Stick to informal vocabulary and phrasal verbs for speech, and save the big words for writing. 🎓

Can I use "I" or "We" in my academic IELTS essays?

Sopheak Pich Teacher 3 hours ago

Generally, you should avoid "I" and "We" in academic writing because it makes the essay too personal (informal). Instead of "We see that...", use the passive voice: "It can be seen that...". The ONLY time you should use "I" in IELTS Task 2 is in the introduction or conclusion to clearly state your personal opinion (e.g., "In my opinion, I believe..."). 💡
