roughly 'not any', but the exact sequence is generally not idiomatic in standard PortugueseFor learners, this is usually not a fixed expression to use as-is. In standard Portuguese, não and nenhum commonly occur in the same clause with other words between them, as in Não tenho nenhum dinheiro. The exact contiguous sequence não nenhum is typically avoided or only discussed metalinguistically.
PO: Em português padrão, não nenhum quase nunca aparece sem outras palavras no meio.
EN: In standard Portuguese, 'não nenhum' almost never appears without other words in between.
