soluble

the word soluble originates from the latin verb 'solvere', meaning to loosen, untie, or dissolve. the suffix '-bilis', which forms adjectives expressing capability, was attached to create the late latin term 'solubilis', meaning 'able to be loosened or dissolved'. this term passed into middle english via old french. the core logic of the word has remained remarkably consistent, moving from the physical concept of loosening bonds (as in dissolving a solid) to the more abstract idea of resolving or solving a problem.

Structure: solu (loosen, dissolve) + ble (able to be) solu is from latin 'solvere' (to loosen, dissolve). ble is an english adjectival suffix from latin '-bilis', indicating capacity or susceptibility.
