When I typed ain't meaning in the search bar at Google, a result from the New Oxford American Dictionary appeared with the following example:
They ain't got nothing to say.
I have my doubts as to whether the use of the word nothing is correct or not.
Af far as my knowledge concerns, the sentence should be something like this: They ain't got anything / something to say.
Am I right? The word nothing is negative, and the word ain't is negative, too. We should not use two negatives, at least in this example, can we?
When they say: They ain't got nothing to say, it sounds like they have something to say!!
