Questions & Answers about Duermo bien por la noche.

Why is the word for "I sleep" duermo instead of "dormo"?
The dictionary form of the verb "to sleep" is dormir. In Spanish, some very common verbs have a vowel change in the middle when you change them to match the speaker. For dormir, the o changes to ue in the "I" form, making it yo duermo. You will see this happen with other verbs too, like almorzar (to eat lunch) becoming almuerzo.
Why use bien here instead of bueno?
Bueno means "good" (it describes a noun, like a good book or a good friend), while bien means "well" (it describes how an action is done). Because you are describing how you perform the action of sleeping, you must use bien.
The English translation says "at night." Why does the Spanish use por here?
To talk about general parts of the day—like "in the morning," "in the afternoon," or "at night"—Spanish uses the word por. So, "at night" or "during the night" is expressed as por la noche.
In this lesson we are learning to say exact times like a las diez (at ten). Can I use por la noche with an exact time?
No, and this is a common mix-up! If you want to say "at 10:00 at night" (10:00 PM), you switch to de and say a las diez de la noche. You only use por la noche when you are talking about the night in general, without a specific hour on the clock.
