What does “@“ sign mean in phonology or historical linguistics?

I saw “*@” in the context of restriction.

    Please add an example of the context where you encountered that sign (with citation, if possible). – jk - Reinstate Monica Sep 10 '20 at 12:14
  • Thank you for commenting ! I only saw @ sign and no example. – gengosuki Sep 18 '20 at 11:50

it's the X-SAMPA symbol for schwa. X-SAMPA was a system for representing the IPA using only ASCII. Now that unicode has become so ubiquitous it's largely obsolete, but you do still occasionally come across it

  • Thank you for answering! I understood. – gengosuki Sep 18 '20 at 11:52
