Jimmer meaning

(North Wisconsin and Yooper) Alternative form of James, usually a diminutive, but is also occasionally a given name. An odd quality of this name is that it can often take a definite article the (da in yooper dialects,) unlike most english names, I.E. Instead of "Go Tell Jimmer to mow the lawn," "Go Tell the (da) Jimmer to mow the lawn."
