Hello everyone. Could you give me a hint how to identify whether it’s necessary to use the indefinite article with uncountable nouns when they have an adjective with them? Should I always use the indefinite article with an uncountable noun if it has an adjective? Why are the uncountable nouns “trouble” and “immorality” have the indefinite article in the following sentences? I am in a big trouble and I need your suggestion and advice. Fr. Wipfler stated his view that impunity is not only the absence of justice, it is also a sin and a terrible immorality.
