Questions & Answers about Завтра будет минус один градус, там будет морозно и ветрено.
How does the future tense work in the phrase будет морозно и ветрено?
In impersonal expressions, the future tense is formed by using будет (the neuter/third-person singular future form of 'to be') followed by the predicative adverb ending in -о. English needs 'it' to say 'it will be freezing', but Russian just uses будет plus the adverb.
Why isn't there a dative pronoun (like мне or нам) in this impersonal expression?
While you use a dative pronoun to express how a specific person feels (like мне будет морозно for 'I will feel freezing'), you leave the pronoun out when describing the general weather or environment. Without a dative pronoun, it simply means 'it will be freezing' for everyone there.
Why do we use the adverbs морозно and ветрено here instead of adjectives?
When describing the weather in a general way, Russian uses impersonal expressions. Because there is no specific noun acting as the subject (like 'the wind' or 'the frost'), you must use the adverb form ending in -о instead of an adjective.
Why is градус in its basic dictionary form instead of a plural form for temperature?
In Russian, the number dictates the case of the noun that follows it. Because the number ends in один (one), the noun must be in the nominative singular, which is just градус. If it were minus two degrees, the rule for two applies, making it минус два градуса.
