I'm a native German speaker. My daughter is learning (British) English in school. She wrote her first English test and got it back from the teacher now.
I'm surprised the title of the test was
class test nr.1
Is nr. a common abbreviation for the word number in (British) English? I was expecting the abbreviation no.
The answers to these questions didn't help me:
- How to denote a number if # cannot be used? (What are alternatives to # symbol?)
- Why does "No" mean "Number?"
It's not clear to me if
the availability of other abbreviations like "Num." or "Nr." or "#"
means it's available in English or if it'd just be a "natural" choice.
The Wikipedia numero sign page isn't giving a final answer either.
One Minute English shows the use in British English but without the colon.
This answer on englishforums.com claims it's not correct English.
Edit: Changed the wording from correct to common.
