Notes on Meaning
The word volution is highly specialized and is rarely encountered in everyday modern English. Its most frequent contemporary use is in technical, scientific, or poetic descriptions of spiral forms. The archaic sense of "a rolling motion" is largely obsolete. When encountered, it almost always refers to a distinct turn within a larger coiled structure.
