themeless
Lacking central subject
Themeless describes something lacking a unifying theme or central subject.
A themeless party has no costume or decorating concept.
In crossword puzzles, a themeless grid contains no connected entries or wordplay pattern—just individual clues without an organizing principle.
The word often implies something feels scattered or unfocused: The album was themeless and forgettable.
