N OUNS Words that name things or living things in a general way are called “nouns.” The word noun is a noun itself, as is word in this sentence (and sentence too). Nouns that name speci c individual things or living beings are called “proper nouns” and are usually capitalized to distinguish them from common nouns:Fritters was a cat, and Chris is sad that the pet died The proper nouns in the example are “Fritters” and Chris while the common nouns are cat and pet See capitalization. P REPOSITIONS Another type of word that links other words together in relationships is called a “preposition.”In the preceding sentence, “of and “in” are prepositions that “govern” nouns. Prepositions can also link pronouns, phrases, clauses, and other sets or kinds of words I found three errors in what you said The object of the preposition in in the example is the clause that follows it. Pronouns that are the object of prepositions often change form to show that they are in the objective case: The librarian handed the book to her.”
