Serija

Serija is a noun used in several South Slavic languages, notably Croatian, Serbian, Bosnian, and Slovenian, to denote a series or sequence of related items. It can refer to a television series, a film series, a book series, or a chronological progression of events. In mathematics and statistics, serija denotes the mathematical concept of a series, the sum of the terms of a sequence, which may be finite or infinite.

The word is cognate with the Latin series and the Romance forms such as Italian serie and the English term series. In everyday use, the sense depends on context: media discussions often distinguish a whole set or run (for example, a TV serija or književna serija) from a single installment or episode, which is typically called an epizoda.

In practice, serija appears across several domains. Common phrases include TV serija for a television series, filmska serija for a film franchise or series, and književna serija for a book series. In mathematics, serija is the standard term for a series, as in sums like a geometric serija, and is treated as a formal concept alongside sequences (nizovi).

Notes on usage: while serija generally refers to a connected collection, the exact meaning can shift by language and context. Some contexts may prefer more specific terms such as epizoda for an individual installment or niz for a sequence, depending on whether the emphasis is on the whole set or on the order of elements. Overall, serija serves as a versatile, neutral term for categorized groupings linked by a common theme or progression.
