What does saltation mean?
Saltation means a sudden leap, bound, or transition. Its general literary sense emphasizes abrupt movement, often with an implication of energy or unpredictability: a dancer may end a passage with a saltation, while a sudden shift in public opinion can be described as political saltation. In physics and geomorphology, the term has a more precise meaning: particles move through a fluid or loose material in irregular hops rather than passing smoothly or remaining entirely at rest. The word is formal and less common than “jump,” “bound,” or “transition,” but it is useful when the abruptness of an action or change deserves emphasis. Its specialized particle sense is common in technical writing about windblown sediment, dust, and granular materials.
An abrupt leap, bound, or movement.
"The foal's sudden saltation startled the horses nearby."
A sudden or dramatic transition in level, status, or circumstances.
"The election brought about a saltation in the country's political landscape."
The movement of particles in a fluid or loose material through a series of irregular hops.
"Saltation of sand grains continued as the wind strengthened."
This is a specialized term used in physics, sedimentology, and related fields.
The plural is used for individual leaps or abrupt transitions, as well as for multiple instances of the phenomenon.
"The animal's powerful saltations carried it across the ravine."
From the same Latin idea of leaping that gives us “salient,” “assail,” and even “salute,” saltation is the science of moving in sudden hops.

Where does saltation come from?
Saltation comes from the Latin saltatio, a noun formed from saltare, “to leap.” The same Latin root underlies words such as salient, meaning “prominent” or “leaping,” and assail, originally “to leap upon.” Over time, the word developed from the literal sense of leaping into broader senses involving abrupt movement and transition.

How saltation is actually used
The word is formal and relatively uncommon in general prose. Its specialized sense in physics and geomorphology is technical, while figurative uses often suggest a sudden or dramatic shift rather than a gradual change.
