Root Explanation

Aggradational → It is formed from "ag-" (meaning to or toward) and "gradus" (meaning step or degree) combined with the suffix "-ational" (indicating a process or action). The word describes a process that involves the accumulation or increase of material, often in a geological context, suggesting a movement toward a higher level or degree.

Memory Tip

Think of 'moving toward' ('ag-') a 'higher step' ('gradus') — this helps you remember that 'aggradational' refers to a process of accumulation or increase.
