Right now, I have a community wiki question on the main (non-meta) site regarding language differences between english dialects
There's a few comments to take it to meta, a pointer to the glossary (which I'm not a fan of for this sort of knowledge management), two votes to close, and three upvotes for it.
I admit, it's a rather broad question but at what point do questions about cooking vocabulary stop being about cooking and off-topic? Some might not even realize that they're actually questions about terminology:
I found a recipe that calls for (ingredient). What is it, and can I substitute something else for it?
I've recently moved to (country) from (other country) and when I ask in the market for (item) they keep trying to show me (item 2), and when I insist that's not an (item), they look at me like I'm crazy. How do I ask for (item)?
I went to a restaurant when I was in (country) and I ate something that they called (term), and it was delicious. Where can I get it in (other country)?
If you want specific examples:
I found a recipe that calls for (crushed up boiled sweets). What are they, and can I substitute something else for it? (happened years ago; Google at the time was of no help, I used life savers, which looks like I guessed right)
I've recently moved to (US) from (the UK) and when I ask in the market for (biscuits) they keep trying to show me (scones), and when I insist that's not an (biscuit), they look at me like I'm crazy. How do I ask for (biscuits)?
I've recently moved to (US) from (the UK) and when I ask in the market for (shortbreads) they keep trying to show me (biscuits), and when I insist that's not an (* shortbreads*), they look at me like I'm crazy. How do I ask for (shortbreads)?
I went to a restaurant when I was in (China) and I ate something that they called (fragrant meat), and it was delicious. Where can I get it in (the US)?
I went to a restaurant when I was in (the Netherlands) and I ate something that they called (pardenrukvlies) (not sure how to spell it), and it was delicious. Where can I get it in (the US)?
Yes, most of these can be cleared up with search engines these days (even the last question, thanks to improved search algorithms and automatic translation) ... and the last weren't just English dialects, but it's late and I'm tired ... I'll see if I have an english-to-english translation in the morning)
update : I know about the glossary project, and I don't like it, specifically because of this issue. If it were being maintained by a single person, it might not be as bad, but all it takes is one person thinking that defined something wrong, or spelled something wrong, and removing all of the British or American versions, and if you don't realize that's the issue, you get one person trying to revert the changes back rather than merge them together, etc.
The question is -- where is the line for acceptable and not acceptable? If I phrase a question such that I know it's simply an issue of vocabulary, are they automatically of-topic because there's this glossary effort, no matter my personal feelings about the suitability it?
