- adj. not easily solved
Sorry, no etymologies found.
The longer the case was probed, the deeper became its unsoluble aspects.
The antiquated view of Du Bois-Reymond (1872) -- that human consciousness is an unsoluble "world-riddle," a transcendent phenomenon in essential antithesis to all other natural phenomena -- continues to be upheld in numerous writings.
I would have made the seams unsoluble and only the fabric soluble.
