Questions & Answers about Rano była duża mgła.
Why doesn't the sentence have a word for "there" like the English translation "there was"?
In Polish, you don't need a placeholder word like "there" or "it". The verb była simply means "was", and the subject is mgła (fog). So the Polish sentence literally says "Morning was big fog."
Why is the verb była instead of był or było?
The verb must match the gender of the subject. The subject here is mgła (fog), which ends in -a and is a feminine noun. Therefore, the verb takes the feminine past tense form była.
Why is it just rano and not something like w rano for "in the morning"?
The word rano is an adverb of time meaning "in the morning", so it already contains the idea of "in". It never needs a preposition like w (in). You just use rano all by itself to say when something happened.
Why does the sentence use duża (big) to mean "thick" fog?
Different languages have different natural pairings for words. While English speakers talk about "thick" or "heavy" fog, Polish speakers describe it literally as "big fog" (duża mgła).
