resolution
This word carries a strong sense of closure and clarity. Whether it is a visual image becoming sharp or a conflict reaching a conclusion, the underlying feeling is the transition from a blurred or chaotic state to one of precision and certainty. In a personal context, it suggests a mental pivot. It is not just a wish or a hope, but a formal commitment of the will. Using this word in a professional or legal setting implies a definitive end to a process, leaving no loose ends.
Countable when referring to a specific decision or a technical measurement (a resolution). Uncountable when referring to the abstract quality of being determined (she has resolution).
