The botanist described the involuted petals as a distinctive trait of the species.

The petals were involuting slowly as the flower began to close for the night.

The involutive linear operator, when applied twice, yields the identity on the vector space.

He traced the ancient pattern involutely, unaware of the symbol's deeper meaning.

In the study of linear operators, involutivity imposes strict constraints on the spectrum, forcing eigenvalues to be ±1.

After years of chasing outward success, he found that self-involution was the only way to rebuild his sense of purpose.
