When to Use "е" and "и" in Derived Prepositions

In Russian, the derived prepositions "е" and "и" are used in different contexts.

"Е" is used in the following cases: - When the preposition is derived from the word "в" (in, into) or "на" (on, onto). - Examples: во дворе (in the yard), во льду (in the ice), на острове (on the island), на огонь (on the fire).

"И" is used in the following cases: - When the preposition is derived from the word "в" (in, into) or "на" (on, onto) and is followed by a word starting with a vowel or "й". - Examples: в огне (in the fire), в океане (in the ocean), на острове (on the island), на огне (on the fire).

In summary, "е" is used for derived prepositions from "в" and "на" in general, while "и" is used when the derived preposition is followed by a word starting with a vowel or "й".
