Coheiress → It is formed from "co-" (meaning together) and "heiress" (from Old French *heritiere*, meaning a female heir). The word refers to a female who shares inheritance rights with others, indicating a joint status as heirs.
Think of 'together' ('co-') and a 'female heir' ('heiress') — this helps you remember that a coheiress is a woman who shares inheritance rights.
