The words "var," "och," and "vart" are Swedish words with distinct meanings and uses:

• [var](javascript:void(0)) means "where" in English and is used to refer to a location or position where something or someone is. For example, "Var är katten?" means "Where is the cat?" It answers questions about location or place, often replaceable with "here" or "there" in Swedish to check correct usage.
• [och](javascript:void(0)) means "and" in English. It is a conjunction used to connect words or phrases, just like in English.
• [vart](javascript:void(0)) means "where to" or "whither" in English and is used to indicate direction or movement toward a place. For example, "Vart är du på väg?" means "Where are you going?" It answers questions about direction or destination and can be checked by substituting "hit" or "dit" (to here or there) in Swedish.

In summary:

• [var](javascript:void(0)) is for location/static place ("where is something?")
• [vart](javascript:void(0)) is for direction/movement ("where to?")
• [och](javascript:void(0)) simply means "and".

A handy mnemonic is: answer with "här" (here) or "där" (there) = use [var](javascript:void(0)); answer with "hit" (to here) or "dit" (to there) = use [vart](javascript:void(0)).
