in-SOL-y-uh-bl/ɪnˈsɒljəbl/

Insoluble means impossible to solve; of a substance, that will not dissolve: an insoluble problem, an insoluble salt. Dissolve (already in the dictionary) is the chemistry opposite; a collage is design, not a cap.

Meaning

Impossible to solve; of a substance, that will not dissolve.

Examples

• “An insoluble clash with the occupancy cap is not fixed by a collage.”
• “Unsolvable is the puzzle twin. Insoluble (chemistry) will not dissolve. A collage is art. A cap is a certificate. Keep the figure; hang the collage on the stairs.”

Good to know

Unable to be solved (also: will not dissolve). Puzzle twin: unsolvable. A collage ≠ a cap.

Near in meaning

unsolvable, irresolvable, intractable
