What is the possessive form of nouns ending in silent for example The Name Dubois?

The possessive form of nouns ending in silent "s" like "Dubois" is formed by adding an apostrophe and an "s" - Dubois's.

Here's why:

* General Rule: The possessive form of most singular nouns is created by adding an apostrophe and an "s."

* Exception: If the singular noun already ends in an "s", you can add just an apostrophe (e.g., "Charles' book") OR add an apostrophe and an "s" (e.g., "Charles's book"). Both are considered grammatically correct.

* In the case of names ending in silent "s," the traditional way is to add both the apostrophe and the "s".

So, the possessive form of "Dubois" is Dubois's.

Example:

* "The Dubois's house is on the corner."
