prograd

Prograd is a term used in multiple disciplines as a shorthand or proper name, and there is no single, universally accepted definition. The meaning of prograd is therefore highly context-dependent.

In astronomy and planetary science, prograde motion describes movement in the same direction as the rotation of the primary body. Researchers sometimes use the form prograd as informal shorthand to indicate a prograde sense of motion or orientation in data sets, simulations, or when labeling orbital elements. This usage is not standardized and may vary by project.

In geology and sedimentology, progradation refers to the seaward growth of a shoreline or delta caused by sediment deposition. The adjective progradational describes deposits, shorelines, or regressive sequences formed during such growth. In field notes, diagrams, or literature, prograd can appear as an abbreviated form of progradational.

In contemporary branding and education technology, ProGrad has been used as a name for programs, courses, or software products. The exact scope and offerings of any specific ProGrad program depend on the organization behind it.
