My grandparents lived and worked in Ghana and an expression that has been frequently used in our family is nneema nneema. This is in the Ghanaian Akan people’s Twi language. This translates to ‘goods’, and in the family was used to refer to stuff or household junk. We used the pronounciation yaman yamma, which appears to be close enough.
