Questions & Answers about È un paradigma che non conosco.
Why does the sentence use un paradigma instead of una paradigma if the word ends in -a?
Paradigma is one of the special nouns of Greek origin ending in -ma. Even though it ends in -a, it is completely masculine in Italian. That is why it takes the masculine indefinite article un instead of the feminine una, just like un problema or un sistema.
If I wanted to talk about multiple paradigms, how would this word change?
Why use conosco here instead of so for "I know"?
Can I drop the word che like we often drop "that" in English?
No. In English, you can say "It's a paradigm I don't know," dropping the connecting word. In Italian, you can never drop the relative pronoun. You must always include che to link the two halves of the sentence.
