Questions & Answers about Иногда я боюсь темноты, особенно ночью.

Why is темноты in the genitive case instead of the accusative?

The Russian verb бояться always takes its object in the genitive case, not the accusative. So “fear of darkness” is боюсь темноты, not боюсь темноту.

Why is ночью in the instrumental case, and how does it work here?

Many Russian time expressions use the instrumental case to mean “at [time].” The noun ночь (night) in the instrumental becomes ночью, meaning “at night” or “during the night.” It functions as an adverbial modifier of time.

Is the comma before особенно ночью mandatory, and why is it there?

Here особенно ночью is a detached adverbial phrase adding emphasis (“especially at night”). When such clarifying or emphatic modifiers follow the main clause, they are typically set off by a comma to indicate a slight pause and highlight the nuance. The comma is recommended for clarity but in very casual speech it might be dropped.
