Perhaps an Americanized spelling of Dutch van der Woord, a habitational name from places named Woord, Woerd, or Word.
hope this helps.

the nationality is roman.....
surnames were commonly used two thousand years ago in areas occupied or influenced by the Romans.
Other areas of the world were slower to begin using surnames, but they were coming into regular use by the time of the Middle Ages, first by the nobility, then by the gentry. After the fall of the Roman Empire, Ireland was one of the first countries to adopt hereditary surnames, and Irish surnames are found as early as the tenth century.3

Surnames are generally derived from one of four sources: the name of the person's father (patronymic), the person's locality, the person's occupation, or a descriptive nickname for the person. When they were created, they answered one of the following questions: Who is this person's father? Where is this person from? What does this person do for a living? What is his or her most prominent feature?

The patronymic name suggests the name of the father or grandfather by the use of some form of "of." In Ireland, "Mac" means "son of," while "O" means "grandson of." When "d’" or "di" is found in an Italian surname, it signifies "son of." In Czechoslovakia, Pavlov is the "son of Paul." This naming pattern can be seen clearly in Sweden, where each subsequent generation followed suit: Hans Peterson would be the son of Peter; Hans Peterson's son would be called Jan Hansen. (On the female side, the daughter of Hans would be called Hansdotter.) A similar situation can be found in the New World, in naming patterns in Dutch New Amsterdam.4 Some common patronymics are Robertson, Anderson, Williamson, and Johnson.

A name (on its own) doesn't have a nationality.
If you take a look at the 1880 census, there are many persons with the name... some who came from England, others from Ireland, Scotland, etc.
The PERSON with the name will have a nationality, or more accurately, a location where his ancestors came from. Your ancestor with the name could have come from any of these places.. you won't know for sure without researching your ancestry.

I think it would be English

My last name is Word.. I have been curious about this as well! I read somewhere that it could be derived from old english ward or warden... meaning guard- an occupational surname.

The meaning of the surname WORD is - dweller at, or near a thicket or winding brook.
