Etymology

insoluble = in<not> + sol<loosen> + uble<able to>

  • in (prefix): from Latin "in-," meaning "not" or "opposite of."
  • sol (root): from Latin "solvere," meaning "to loosen" or "dissolve."
  • uble (suffix): variant of "-able," meaning "capable of."

Etymology Origin:
The word "insoluble" originates from Latin "insolubilis," combining "in-" (not) + "solubilis" (dissolvable). The root "solvere" (to loosen) also gives rise to words like "solve" and "dissolve." Over time, "insoluble" evolved to describe both physical undissolvability (e.g., in chemistry) and metaphorical unsolvability (e.g., problems).

Examples
  1. Oil is insoluble in water, forming distinct layers.

  2. The detective faced an seemingly insoluble mystery.

  3. This chemical compound remains insoluble under normal conditions.

  4. Philosophers often debate insoluble questions about existence.
