Zugzwang is a German word meaning 'compulsion to move'. In chess, it refers to a position where any move a player makes will result in a disadvantage. If it were legal to skip a turn, the player would do so, but since a move is mandatory, they must worsen their own position. This is most common in endgames.

Frequently Asked Questions
Zugzwang is most common in endgames, especially king-and-pawn endgames, where each side has few remaining moves and every move has consequences.
Not always. Zugzwang means any move worsens the position – that could translate to losing material, losing the game, or simply giving up a draw. In some cases it 'only' loses a tempo.
Mutual zugzwang (also called reciprocal zugzwang or trébuchet) is a rare endgame position where whichever side moves loses. It's a favourite theme in composed studies.
