Common mistake
Saying "I joined the room" when you mean you physically walked in — correct is "I entered the room." "Joined the room" in English implies you became part of a group already in the room (like a video call: "joined the meeting"). Also: "I entered the team" sounds odd — correct is "I joined the team" (you became a member).
Trick to remember it
Simple question: is it a physical place with walls? "Enter". Is it a group, organization, or activity? "Join". In video calls and virtual meetings, "join the meeting/call" is correct, not "enter the meeting" (even though you technically enter a virtual space).
Quick rule
Join = become part of (group, team, organization). Enter = go into (physical place, system).
Did you know?
In the video call era (Zoom, Teams, Meet), "join the call / join the meeting" became essential vocabulary. No platform says "enter the call" — it is always "join". This modern use of "join" for virtual meetings is exactly the same as "join the club / join the army" — you become part of a temporary group.
