The story

The root q-l-y is that of "to fry" and "to roast": alkali was what was left after burning certain salt-marsh plants. Hence alcalino (alkaline) and alcaloide (alkaloid).La raíz q-l-y es la de «freír» y «tostar»: el álcali era lo que quedaba al calcinar ciertas plantas de saladar. De ahí alcalino y alcaloide.
