Questions & Answers about Non è un arrivederci, è un addio.
Why is arrivederci used with un here? Isn't it just a greeting?
What is the difference between arrivederci and addio?
Since addio starts with a vowel, why isn't it written as un'addio with an apostrophe?
The indefinite article un never takes an apostrophe before a masculine noun like addio. You only use un' (with an apostrophe) before feminine nouns starting with a vowel, because it stands in for una (like un'amica).
How do we say "It" in "It is not..."? I only see Non è.
Italian generally drops subject pronouns (like I, you, he, she, it) because the verb tells you who or what is doing the action. È means "is", and the "it" is simply understood from context.
