about, around

[tree123]

Previously in order no to repeat 'about' / 'around', I alternatively used them in the same piece of writng. Now I just happened to find out[1] 'about' is British English, and 'around' is American English. And you folk have told me not to mix American and British English together. So am I wrong to mix the words in my writing?

e.g. I get up at around six am, and have my breadfast at about seven am. (wrong)?

I'm not very sure.

In the US we use both.

 

[Rover_KE]

We use both in the UK, too.

Also, tree, in American English you're more likely to see 6 A.M. and in British English 6am.

No, that's not right. I imagine you're looking at this very specific use:

mainly UK
(US usually around)

• positioned around a place, often without a clear purpose or order:

Their belongings were flung about the room.

I had thought the rule was applied in every case. Thank you all for your clarification.

Yup. In the US, we fling our clothes around the room and then complain about how messy it is.

But we agree with the Brits that turnabout is fair play.
