"Var", "eller" and "vart" are Swedish words that relate to questions about location and direction. "Var" is used to ask about a static place or position, meaning where something or someone is located. "Vart" is used to inquire about a direction or movement—where someone is going or which way they are heading. The word "eller" means "or" in Swedish, used to offer options or alternatives in questions or statements.

Explanation of each word

• Var : Used when asking about a non-moving, fixed location.
  Examples:
  Var är du? ("Where are you?")
  Var ligger biblioteket? ("Where is the library?")
  It often relates to questions about where someone or something is situated, without any movement involved.

• Vart : Used when asking about movement or direction toward a place.
  Examples:
  Vart ska du åka? ("Where are you going?")
  Vart är du på väg? ("Where are you headed?")
  It indicates a destination, or where someone or something is moving toward.

• Eller : Means "or" and is used to offer options or alternatives within questions or statements.

Together, these words help differentiate between static location ("var") and movement/direction ("vart"), which is crucial for clarity in communication in Swedish.
