Step-by-step explanation:
When a speaker says "Omina show ya allah the things yer gonna be needin' to buy," the speaker is using a dialect or form of English known as African American Vernacular English (AAVE). AAVE is a variation of English spoken predominantly by African Americans. It has its own grammatical rules and pronunciation patterns that differ from Standard American English. In this particular sentence, the speaker is using nonstandard English words and grammar, such as 'Omina' instead of 'I'm going to', 'ya' instead of 'you', and 'yer' instead of 'your'. These features are characteristic of AAVE.
