Questions & Answers about Sono le quattro e mezzo.
Why does this sentence use Sono le instead of a singular "It is" like È?
Is there a reason we say le quattro rather than just quattro?
Yes! When telling time, you always need the definite article before the number. Because the word for "hour" (ora) is feminine, you use the feminine plural article le. The only exception is one o'clock, which is singular (l'una).
Wait, shouldn't "half" be feminine (mezza) to match the hours?
How does the structure here compare to the English "half past four"?
