Root Explanation

Subindex → It is formed from "sub-" (meaning under or below) and "index" (from Latin "index", meaning a pointer or indicator). The word "subindex" refers to an index that is subordinate or under another index, indicating a secondary level of categorization.

Memory Tip

Think of something that is 'under' ('sub-') a main 'pointer' or 'indicator' ('index') — that's why a subindex is a secondary index.
