By vs Until

Quick English tip — confused between BY and UNTIL? Let’s fix that fast! If you say “I’ll finish by 5,” it means anytime before 5 — or exactly at 5, but not after. Think of it as a deadline. But if you say “I’ll work until 5,” that means you’ll keep working the whole time — and stop exactly at 5. It’s about duration. Remember this simple trick: BY = deadline, UNTIL = duration. So, if you want to relax, finish by 5 — if you want to keep working, go until 5! Watch the full video and join our online spoken English classes today!
