## AI Etymology
involutional comes from involution (from Latin involvere 'to roll up', from in- plus volvere 'to roll') plus the adjectival suffix -al. Morphologically, the ending is part of the etymology: the suffix is attached to the older base named in the history, producing a later English derivative. In present English, the adjective sense is "relating to a shrinking or degenerative decline of an organ or faculty with age", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as involution and involute, and in derivatives such as involutionally. Its semantic neighborhood includes regressive, degenerative, atrophic, and declining, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin involvere and Latin volvere.
