There is a straightforward query provided by Michael Mrozek with SEDE

Alarming Results

There are 607 tag pairs on Stack Overflow which differ by only a hyphen!!

SELECT a.TagName AS First, b.TagName AS Second
FROM Tags AS a, Tags AS b
WHERE a.Id < b.Id
AND REPLACE(a.TagName, '-', '') = REPLACE(b.TagName, '-', '');​

Call to Arms

After upvoting his awesomeness, please make synonym suggestions. Note that this data is a month old, so -- for example -- and were already proposed, but still need votes!!

And, lest you think this is on a problem on Stack Overflow, Programmers has six tag pairs and I'm sure there are plenty others out there -- Super User has 29. Server Fault has 55. Let's get those badges!

And also Plurals

After learning a bit more SQL, I've also constructed a query for tags which differ by only ending in 's' or 'es'. There are currently 614 tag pairs on Stack Overflow which fit this criterion. Now it does incorrectly catch (, ) as well as (, ), but it certainly has plenty of synonyms to suggest!!

    Only if the tag synonym main page contained those vote buttons so that I don't need to click a zillion of times to vote every individual synonym..

  • Speaking of synonyms. . .Perhaps call-to-arms could be a synonym for posse, or vice versa? Aug 19, 2011 at 20:56

    I liked call-to-arms, but either way works for me. ;O)

    Here is a link to see all synonym suggestions (on Stack Overflow) where you are allowed to vote: stackoverflow.com/tags/synonyms?filter=suggested. (This includes those where you already have voted, though.) Aug 20, 2011 at 0:59

    Change the vote threshold then. I stopped suggesting synonyms because nothing ever happened... why waste my time?

Among the many proposals generated by these queries, here's a three -> one:

though only has 33 questions, the:

  • phrase is two words, meriting the hyphen
  • plurals tend to be preferred as 'all-encompassing'

And the same goes for:

though only has 2 questions. So perhaps instead?

Update: And for...

though only has 31 questions?

    I'd love to see if customcomponents, customcomponent and custom-component could all get merged/synonymized to a new tag custom-components.
