According to our FAQ:
You should only ask practical, answerable questions based on actual problems that you face.
Since all of our questions should be practical, does it make sense to have a practical tag?
From looking at the motley crew of posts currently tagged with practical (including a question of mine edited by someone else), there isn't a strong unifying meaning in how it's used, so it could be deleted.
But I also think a tag to outline Japanese expressions useful for "survival" or "everyday-life" situations, as opposed to more scholarly or general questions, could have its use. Dunno if there is a better match than 'practical' for that.
I am actually in favor of keeping the practical tag to tag questions that deal with practical usage of idiomatic expressions and greetings rather that the finer, theoretical and linguistic aspect of the language. Since many of the questions are dealing with explaining how grammar rules work, difference between word choices, translation of phrases etc, it's good to have a way to distinguish questions that are really asking how to use specific expressions in practical day-by-day usage, such as:
The tag is a bit fuzzy. I'm not sure who invented it but I tried to use it since I saw it struggling. I used it to tag "Japanese in action" questions. When an aspect of Japanese speech or writing is put to a specific practical use. Think of it as "applied" Japanese whereas most of the grammar/vocabulary discussion could be thought of as "pure" Japanese.
I don't have my heart set on saving it but it could be worth putting a bit of thought in to see if it or something like it could be hammered into something useful before tossing it away outright.
How about replacing it with
phrase-requests where applicable?
I added a
phrase-requests tag to a question before looking around very much, and then found that most of the phrase-request questions were tagged with
phrase-requests is pulled from English Language & Usage, where they've been using the tag since this April. Though not as popular as its sister tag,
single-word-requests (debate over its usage here), I think it's safe to say it's workable as a tag.
