Questions & Answers about Сегодня всё небо очень яркое.
Why do we use всё here instead of весь?
The word всё must match the gender of the noun it describes. Because небо (sky) is a neuter noun, we use the neuter form всё. If it were a masculine noun, we would use весь.
In the vocabulary, всё means "everything." Why is it translated as "the whole" here?
When всё is used on its own as a pronoun, it means "everything." But when it is placed directly in front of a singular noun like небо, it acts like an adjective meaning "the whole" or "all of the." So, всё небо translates to "the whole sky."
Is it important to write the two dots over the ё in всё?
Yes, it is very helpful here! This distinguishes всё (the neuter form meaning "the whole" or "everything") from все (the plural form meaning "all" or "everyone"). Russian speakers sometimes skip the dots in everyday writing, but as a learner, paying attention to them prevents confusing these two very common forms.
Why does яркое end in -ое?
The adjective яркое (bright) must agree with the noun it describes, which is небо. Since небо is a neuter noun in the nominative case (acting as the subject of the sentence), the adjective takes the standard neuter nominative ending -ое.
