I read "How does the tag synonym suggestion feature work?", but I ran into what may be a problem or nothing at all.

casting is most used, so I suggested type-casting be a synonym.

Then I suggested typecasting also be a synonym, and I got a warning, since typecasting is already a synonym suggestion for type-casting.

If type-casting is accepted as a synonym for casting, does typcasting automatically become a synonym for casting too.

In other words, does it matter what order you suggest synonyms in?

If you believe [casting] is a better tag than [type-casting], could you elaborate? I'm not strongly attached to one or the other, but given how close between my post and this, I am definitely curious. – Gnome Sep 18 '10 at 3:13
@Gnome - I don't. I didn't realize it mattered which one you suggest a synonym to, since synonym means equal..... Also, you can't suggest casting as a synonym on the type-casting page, since casting is more frequent. – Peter Ajtai Sep 18 '10 at 3:26
It slightly matters: the "master" tag is what gets used from that point forward and should be the "correct" name. Re the latter, that's why I had to post on Meta for a moderator to do the retag (they have tools to retag all at once) rather than just make a synonym suggestion. – Gnome Sep 18 '10 at 3:29
@Gnome - Thanks. I see. I just didn't quite get the "master" tag concept. – Peter Ajtai Sep 18 '10 at 3:32

I believe no synonyms will change, but the tag can be rewritten multiple times. For example, if your proposal succeeds and type-casting -> casting, typecasting -> type-casting will still show up in the synonym list. Attempting to use the tag typecasting will result in the tag casting, since typecasting -> type-casting -> casting

So theoretically, it'd be bast to propose both type-casting and typecasting as synonyms on the casting page? – Peter Ajtai Sep 18 '10 at 3:29
@Peter You can't, for the reason you said in the second half of your question – Michael Mrozek Sep 18 '10 at 3:43
