For example, she will experience life to its fullest extent coterminous with her mother.

According to the Merriam-Webster dictionary, coterminous is defined as:

“Existing or occurring at the same period of time” or “occupying the same space”.

The word coterminous comes from the Latin term “conterminus” where “con” means “with” and “terminus” means “border” or “end”.

When you use the word coterminous, you are suggesting:

Non-Coterminous Definition 

Non-coterminous means that the boundaries, scope, or duration of something is not consistent with another.

For example, the mortgage lender offered the borrower a second mortgage with a term that was non-coterminous with the term of the original loan.

This means that the original mortgage will end at a date prior to the expected term of the second mortgage.

If the lender wanted the borrower’s second mortgage to end on the same date as the original mortgage, then it could have made the second loan term coterminous with the original one.
