Do you zummish?

Posted by John Banghart on June 24, 2010 at 13:54

My grandfather(1896-1980) frequently used the expression "Do you zummish(zoo-mish)? Or just said Zummish?, meaning "do you understand"? I've not been able to find this word anywhere. They lived in north central Pennsylvania with a strong German heritage in the area. Please help if you can. Thanks
