Questions & Answers about Наверное, будет мороз.

Why doesn't this sentence use a dative pronoun, since we are learning impersonal expressions?
In this specific sentence, мороз (frost) is actually a noun acting as the subject. The verb будет (will be) just matches this noun. Impersonal expressions, like нам будет холодно (we will be cold), use an adverb instead of a noun and don't have a real subject. This sentence is a helpful reminder of the difference!
Could I use an adverb and say Наверное, будет морозно instead?
Yes! Морозно is the adverb form meaning 'frosty' or 'freezing'. If you say Наверное, будет морозно, you are using a true impersonal expression, exactly like the ones in this lesson. The meaning is almost exactly the same as будет мороз (there will be frost).
Does the word наверное have anything to do with верно (true/correct)?
It does! Верно means 'true' or 'correct'. The word наверное originally meant 'for sure', but over time its meaning softened. Today, it translates to 'probably' or 'most likely'.
Why is there a comma after Наверное?
In Russian, introductory words that express the speaker's attitude or certainty—like наверное (probably), конечно (of course), or кажется (it seems)—are almost always set off by commas from the rest of the sentence.
