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

- 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).
