vzadu

Vzadu is a Czech adverb of place meaning "at the back" or "behind." It denotes a location relative to a reference point and is used to describe where something is situated within a space, such as a room, a vehicle, or a crowd. The word is common in both everyday speech and written Czech.

In use, vzadu describes position without requiring a separate preposition in many cases, and it can stand with or without a following noun phrase. Examples include: "Dveře jsou vzadu." (The doors are at the back.) "Seděl vzadu ve třídě." (He sat in the back of the classroom.) "Vzadu v autě jsou sedačky." (In the back of the car there are seats.) It is typically contrasted with vpředu, meaning “in front,” to indicate opposite positions.

Etymology and related notes: vzadu is formed from the root zad- meaning back, with a locational usage pattern common in Czech. As with other spatial adverbs in Czech, it is invariable and does not change for gender or number. The term is widely understood across Czech-speaking contexts and can also appear in fixed phrases describing the rear part of a space or object.
