infinitesimally
By tiny degrees
Infinitesimally means by an extremely small amount—so small as to be nearly immeasurable or negligible.
The word derives from infinitesimal, a mathematical term for quantities approaching zero.
In everyday use, it emphasizes how slight a difference or change is: The price moved infinitesimally.
Her expression shifted infinitesimally, but I caught it.
