история

In a sentence

• България има дълга и богата история.

  Bulgaria has a long and rich history.

  In this sentence, the word 'история' (history) is used to describe the historical and cultural past of Bulgaria, functioning as a noun referring to the collection of past events.

• Четох интересна история в тази книга.

  I read an interesting story in this book.

  Here, 'история' switches its meaning to 'story,' denoting a narrative or tale, also a noun.

• Знам цялата история за този случай.

  I know the whole story about this case.

  In this example, 'история' again means 'story,' but this time it describes a recounting or an account of events related to a particular case; it is still a noun referring to a detailed account.
