Here's why:
* "Ward" often signifies a place or a person who is protected or guarded.
* Examples: "Hospital ward," "School ward," "Wardrobe" (where clothes are kept safe), "Ward" (a person under legal protection)
* It can also describe a direction or position:
* Example: "Starboard" (the right side of a ship)
* Sometimes "ward" forms part of a verb:
* Example: "To safeguard," "To reward"
However, "ward" isn't always a noun-forming suffix. It can also be used as a standalone word meaning:
* A district or division of a town or city.
* A person under the care of a guardian.
So, the specific function of "ward" depends on the word it is added to and the context in which it is used.
