Interdental fricatives become alveolar stops: initially:

they>"dey" them>"dem" think>"tink" thin>"tin"

But, if the following cononant is an r: three>"free" throat>"froat" medially: nothing > "nuffin'" brother > "bruvvah" finally: tenth > "tenf" /"tent" mouth > "mouf" /"mout"

Grammar: AUX-deletion (i.e., deletion of the auxilliary verb):

Where Standard English can contract, Black English can delete:

Standard English (informal)	Black English
He's going	He going
I've got it	I got it
He'd be happy	he be happy

Note that where Standard English cannot contract, Black English cannot delete:

*What a fool you're.

*What a fool you.

Iterative/habitual be:

He be coming home at six. (means: "He usually comes home at six.")

Double (or multiple) negation:

"Neither one of us ain't got nuthin' ta lose." (Eddie Murphy, 48 Hours)

"Can't no one tell you you ain't somebody." (Jessie Jackson)

cf. "Nor is this not my nose neither." (Shakespeare)

Morphology and Syntax:

With a numerical quantifier such as two, seven, fifty, etc., Black English speakers may not add the obligatory in Standard English (and redundant) morphemes for the plural: e.g., fifty cent, two foot.

The use of the possessive marker: Where the Standard English speaker says "John's cousin"; the Black English speaker might say "John cousin." The possessive is marked in Black English by the "genitival" position of the noun and its possessor

The third-person singular has no obligatory morphological ending in Black English, so that "she works here" is expressed as "she work here."

Black English sometimes uses ain't as a past-tense marker:

Black English present tense: "He don't go."

Black English past tense: "He ain't go."

Future-tense:

Standard English: "I will go home" Black English: "I'ma go home"

Conditional subordination:

Standard English: "I asked if he did it."; Black English: "I ask did he do it."

Pronoun case: Standard English: "We have to do it." Black English: "Us got to do it."

Preposition: Standard English: " He is over at his friend's house." Black English: "He over to his friend house."
