The word unresolved may describe an argument that has not been solved, a question that remains unanswered, or a decision that has not been made — like the title of “Checkers Champion” after a tie game.
The word unresolved is used for a situation that lacks a resolution, or ending. It can also describe unaddressed emotions, such as anger or sadness, as in the unresolved issues you have toward your hamster ever since it bit your finger. The word unresolved can also be used to describe musical dissonance — if you hear a chord in a symphony that makes you think the song isn’t over, the chord is probably unresolved.
not brought to a conclusion; subject to further thought
characterized by musical dissonance; harmonically unresolved
