Happy Sunday! This week took us from setting breakpoints in a debugger to quantizing models, throttling traffic, elaborating on decisions in meetings, and finally sounding approachable at a networking event. Today we slow down and lock in the five words that mattered most — plus every idiom from the week, so nothing slips away before Monday.

📖 Word of the Day: Roundup

• Word: roundup
• IPA: /ˈraʊnd.ʌp/
• Vietnamese meaning: bản tổng kết, tóm lược lại những điểm quan trọng nhất

  1. “Here’s a quick roundup of everything we shipped this sprint.”
  2. “The Friday roundup email keeps the whole team aligned on priorities.”

🗣 Pronunciation Guide

“Roundup” breakdown — /ˈraʊnd.ʌp/:

• Stress on the first syllable: ROUND-up, not round-UP
• “Round” uses the diphthong /aʊ/, like “found” or “sound”
• “-up” is short and light — don’t over-stress it

Practice sentence (read aloud 3x):

“Before we wrap up this roundup, let’s make sure the whole team is on the same page.”

Notice how “roundup” and “on the same page” fit naturally into one sentence — that’s the goal of a weekly review: combine words, don’t just memorize them in isolation.
