In the song ‘I’ve Been Working on the Railroad’ one of the verses is
"Someone’s in the kitchen with Dinah
Someone’s in the kitchen I know
Someone’s in the kitchen with Dinah
Strummin’ on the old banjo!”
I found out this verse is talking about a Black woman. Apparently, Dinah was slang for women of African American descent. It was usually used in a derogatory manner. Even Sojourner Truth was called Dinah.
I wonder why this name was used as a slang word. Perhaps its connected to the Dinah in the Bible.
Dinah is even used on vintage advertisements
