Questions & Answers about La reunión es a las ocho.
Because ser is used to identify or define something, and here the sentence is stating a scheduled time for the meeting.
- La reunión es a las ocho = the meeting is at eight / the meeting takes place at eight.
- Estar is more for location, condition, or temporary state.
So:
- La reunión es a las ocho = correct
- La reunión está a las ocho = not correct in this context
A useful way to think of it is that Spanish often uses ser when talking about an event’s scheduled time:
- La clase es a las nueve
- El concierto es a las diez
Spanish often uses the definite article more than English does.
- La reunión literally means the meeting
In many everyday sentences, Spanish prefers the article where English may or may not use one depending on context. If you are talking about a specific meeting already known in the conversation, la reunión is natural.
If you said just Reunión es a las ocho, it would sound incomplete or unnatural.
