Do questions in Y!A have to be in Engish?

Now that you mention it not too long ago every language seemed to be allowed. Glad you asked. Thanks

Certainly everything must be in English on an English speaking site otherwise most people would not be able to understand it and it may be rude. If the asker wishes to use another language they should change international sites on the bottom right of the page.

Yes, all questions and answers on the English speaking portals of Answers must be in English unless asking for or giving a translation.

Posting in another language besides English is a violation.

No you can set the language you want

Yes. The Community Guidelines stipulated that all postings have to be in English on Answers sites in the following countries:

1. U.S.

2. Canada (Anglophonic)

3. Australia

4. India

5. New Zealand

6. British Isles (UK and IE)

7. Philippines

8. Singapore

9. Malaysia

The only exception to the rule, however, is when you request a translation for a word or a phrase.

Yes, when posting on ANY of the English language portals of YA. There are other language portals if you look at the bottom right of any question page and click on the "International Sites" link. For US, UK, CA, IN, AU, NZ and a few others (I think) English is the only language that is allowed, other than asking for a translation into/from some other language in the Languages subcategory. 

If they are in a English Speaking Country Site yes they have to be in English you can not type it in a Different Language if you do its Possible someone may Report your Question and it may End up getting taken down

Yes. The questions have to be in English :) .

they have to be in the language of the site in question.

Questions *in* Gaelic or Welsh are not allowed.

There is no "UK-version". All English-speaking portals were merged years ago - and that includes the "India"-portal

On the YA sites that use English, you must use English. Click on International at the bottom right and you will see all the sites. For example, on the Germany site, you must use German.
