whit

This term functions primarily as a rhetorical device to emphasize absolute negation. It is almost exclusively found in negative constructions, such as "not a whit" or "without a whit," to signal that there is zero presence of a particular emotion, quality, or amount. Because it represents an infinitesimal quantity, it is treated as a singular countable unit in these specific idiomatic phrases, though it conceptually refers to a negligible degree of something.
