I'm still waiting for you to explain why you used an adjective ("inutile") as a noun.
Here is an explanation, hoping that you'll learn something worthwhile today: First,
inutile is an adjective and when used in a sentence like "I hate you,
inutile!" is not used as a noun but still remains an adjective as it always is. For you to see clearly, such usage is similar to the statement "How are you,
beautiful?" in which the word beautiful is an adjective and never a noun. "Got it,
stupid?" "I hope so,
inutile." Notice that the highlighted words are adjectives and never a noun, as you claim the usage to be.
This elementary topic shouldn't even merit a discussion here, and how you appear
foolish in raising the question time and again. You even became
more foolish when the answer was given, emphasizing your incompetence on the aspect of grammatical forms and parts of speech.
