Good morning! Today we’re talking architecture — the kind of English you need when you’re explaining why a system is built a certain way, not just what it does. Perfect for design reviews and architecture discussions.
📖 Word of the Day: Decouple
IPA: /diːˈkʌp.əl/ Vietnamese meaning: tách rời, giảm sự phụ thuộc (giữa các thành phần hệ thống)
Example sentences:
- “We decoupled the payment service from the order service so a slow payment provider can’t block checkout.”
- “The team spent a sprint decoupling the frontend from the legacy monolith.”
- “Message queues are a common way to decouple producers from consumers.”

🗂️ Vocabulary Table
| Phrase | Vietnamese | Example |
|---|---|---|
| Single point of failure | điểm lỗi duy nhất | ”That shared database is a single point of failure for the whole platform.” |
| Horizontal scaling | mở rộng theo chiều ngang | ”We handled the traffic spike with horizontal scaling, not bigger servers.” |
| Trade-off | sự đánh đổi | ”Every architecture decision involves a trade-off between consistency and availability.” |
| Bottleneck | nút thắt cổ chai | ”Profiling showed the database was the real bottleneck, not the API layer.” |
| Blast radius | phạm vi ảnh hưởng khi sự cố | ”Splitting the service into cells limits the blast radius of any single outage.” |
🔊 Pronunciation Guide
Decouple — break it into two parts: de- (/diː/, like “dee”) + couple (/ˈkʌp.əl/, like “cup-uhl”). Stress falls on the second syllable: de-COU-ple.
Practice sentence (read aloud 3 times):
“To reduce the blast radius of failures, we decoupled the notification service so a single point of failure couldn’t take down checkout.”
Say it slowly first, focusing on “de-COU-ple,” then speed up until it feels natural.

🎯 Daily Challenge
In your next architecture discussion (real or imagined), use the phrase “single point of failure” at least once — out loud, not just in your head. Notice how it changes the way you frame the risk.
Good luck, and see you this evening for practice! 🚀
