Ways to tell them apart:
Conterminous often refers to sharing a common boundary or endpoint, particularly in geometry or geography.
Contiguous is used to describe objects or areas that are touching or immediately adjacent to each other.
Both words imply closeness, but conterminous emphasizes a boundary, whereas contiguous emphasizes contact.
Remember that conterminous begins with con like connect, relating to a connecting boundary.
Contiguous shares its prefix with continue, suggesting continuation or adjacency.
