Questions & Answers about Ho nascosto la mia sensibilità fino a oggi.
How would I make sensibilità plural if I wanted to say "my sensitivities"?
Because sensibilità ends in an accented vowel, it is an invariable noun. This means the spelling of the noun itself doesn't change in the plural. To make it plural, you only change the article and the possessive adjective to match: le mie sensibilità.
What is the infinitive of nascosto? It doesn't look like a standard past participle.
The infinitive is nascondere (to hide). It has an irregular past participle in the passato prossimo, so instead of taking a regular -uto ending, it becomes nascosto.
Is sensibilità related to the English word "sensible"?
It is actually a classic "false friend." Sensibilità means "sensitivity," and its related adjective sensibile means "sensitive." If you want to say someone is "sensible" (logical or practical) in Italian, you would use a word like ragionevole.
Why does the Italian say la mia sensibilità (the my sensitivity) instead of just mia sensibilità?
Unlike English, Italian generally requires a definite article (la) before a possessive adjective (mia). The most common exception is when talking about singular, direct family members (like mia madre), but for almost everything else—including abstract nouns like sensibilità—the article is mandatory.
