at about 10 o'clock


Senior Member
Hello, everyone,

I'd like to know if the preposition "at" is necessary when you talk about approximate time.

For example:

I went home early - about 10 o'clock.
About 10 o'clock, we stopped at a motorway service station.

In my opinion, it's better to say "at about 10 o'clock", but I found these two examples in a book for learners.

Maybe they are both OK?

(Please, don't answer this unless you REALLY know what you're talking about. I've received answers to other threads that were too vague or even wrong!)

    As a native english speaker I would say both are correct, but "at about 10 o´clock" would be better when written, but it is acceptable to say both in conversation.

    In conversation, anything goes. But for Standard English, you need the preposition. For better results in the quality of the answers to your query, you may want to ask a moderator to move this thread from the Spanish forums to the English Only.
