Learn Italian: Il concetto è ovvio, e ciò implica un fatto. - The concept is obvious, and this implies a fact.

Ciò is a pronoun that means "this," "that," or "it." It is specifically used to refer back to an abstract idea or an entire preceding clause, rather than a physical object. Here, ciò refers to the whole previous statement (that the concept is obvious). While you could also use questo, ciò is slightly more formal and excellent for linking abstract thoughts.

Does ciò ever change its ending to match masculine or feminine words?

No, ciò is invariable, meaning it never changes form. Because it refers to abstract ideas, statements, or concepts, it doesn't have a gender or a plural version. It always stays exactly as ciò.

Does the verb implicare require a preposition before the object?

No, implicare (to imply) takes a direct object, just like in English. That's why it is followed directly by un fatto (a fact) without needing a preposition like di or a in between.

How does the double "v" affect the pronunciation of ovvio?

In Italian, double consonants are pronounced longer and with a bit more emphasis than single consonants. When saying ovvio, you should briefly hold the "v" sound before moving on to the ending.
