What does convolved mean?
Convolved describes something that has been coiled, twisted, or rolled together into a complex, intertwined form. The word derives from the Latin verb convolvere, meaning 'to roll together,' and shares its roots with familiar words such as revolve, evolve, and involve. In its literal sense, convolved appears most often in scientific and anatomical writing — describing, for instance, the tightly folded surface of the brain or the winding structure of certain shells and plants. It also carries a precise technical meaning in mathematics and signal processing, where a function or signal that has been combined with another through the operation of convolution is said to be convolved with it. Although closely related to the much more common adjective 'convoluted,' which typically criticises language or reasoning as needlessly complicated, convolved itself is usually neutral and descriptive. Readers will encounter it chiefly in technical prose, where its exactness makes it preferable to vaguer alternatives like 'tangled' or 'complex.'
Coiled, rolled, or twisted together in an intertwined manner; in technical use, subjected to convolution.
"The fossil ammonite displayed strikingly convolved internal chambers."
Past tense and past participle of convolve: to have rolled or coiled something together, or (mathematics) to have combined two functions via convolution.
"The raw data were convolved with a filter before further analysis."
It comes from the same Latin root as 'revolve' and 'evolve' — literally 'to roll together' — which is why anything convolved looks like it's been wound up on itself.

Etymology of convolved
Convolved is the past participle of the verb convolve, borrowed from Latin convolvere, formed from com- ('together') plus volvere ('to roll'). It entered English in the early modern period alongside related -volve verbs such as revolve and involve. Its cognates therefore include evolve, revolve, devolve, and the noun convolution, all tracing back to the same Latin root for rolling.
