Proper vs. Common NounsThe distinction between proper and common nouns is probably familiar to you from your earlier education.FredandNetherlandsare instances ofproper nouns. A proper noun is a type of noun that refers to a specific person, place, or thing (Evelyn, Cairo, Saturday, etc.)Common nounsrefer to classes of things (cat, trash, stone, etc.) rather than particular ones. All nouns that are not proper are common.The behavior of proper nouns is illustrated in the first two columns of the table above. Most proper nouns behave likeFredin column 1. They do not allow a plural form (*Evelyns, *Cairos, etc.) and do not appear with determiners (*a Baltimore, *some Evelyn, etc.). Some proper nouns do appear in a plural form and with a determiner:the Netherlandsin column 2, for example. But these proper nouns still behave differently from common nouns. There is no contrast in number;the Netherlandscannot be made singular (*the Netherland), and the determiner cannot be varied the way it can with ordinary common nouns:(1)*I went to Netherlands.(2) *I only had time to visit a Netherland.There are also singular proper nouns that take an article, such asthe Kremlin. Here too, there is no plural counterpart (*the Kremlins) and the article cannot be varied.Expressions likePrinceton Universityorthe United States of Americaare frequently called proper nouns as well, but this a somewhat misleading simplification. Remember thatnounis a category label for an individual word. Strictly, the proper nouns here arePrincetonandAmerica.Universityandstatesare common nouns, andunitedis an adjective.

We won't go into them in detail in this course, but we will discuss the patterns that may cause problems for your analysis when we review NP structure at the end of the chapter.

Notes[1] The proper noun does not need to be the head of the proper name. For example, inthe United States of America, the head isstates.
