🧩 resolver = re + solver: be the solver who resolves the problem
From Latin resolvere (re- + solvere, to loosen, untie), the same root as English resolve and solve. A problem is a knot; resolver is loosening it until it comes apart. The English cognates cover nearly every sense: resolve, solve, settle.
