Literal translation
there is enough of that there!
Meaning
enough of that!
Explanation
An exclamation of exasperation built on the locative adverb aqui (here, there), the impersonal turn n'y a (there is) and the quantifier proun, enough, sufficient. The literal meaning points to a quantity reached in a given place, but the figurative use shifts that observation toward moral saturation: enough has been endured, heard, or tolerated. It is the exact equivalent of the French y en a marre, sharing the same impersonal construction and the same abrupt effect. The expression belongs to a familiar register, usually said with a clear tone of irritation, to close off a situation deemed unbearable or to signal that the speaker's patience has reached its limit. The adverb proun (a variant of prou) is very commonly used in Provençal to mark sufficiency, whether in the positive sense of having enough of something or, as here, in the negative sense of too much.
