ID 00546966 Prof. Cynthia Garcia Definitions Pronoun In linguistics and grammar, a pronoun is a word that substitutes for a noun or noun phrase. It is a particular case of a pro-form. Pronouns have traditionally been regarded as one of the parts of speech, but some modern theorists would not consider them to form a single class, in view of the variety of functions they perform. Subtypes include personal pronouns, reflexive and reciprocal pronouns, possessive pronouns, demonstrative pronouns, relative pronouns, interrogative pronouns, and indefinite pronouns. Noun and Numbers There are two numbers in Noun-Number: Singular and Plural. 1. Singular: When we speak about one person and one thing, we use the noun in singular form. Single means one. Plural means many. 2. Plural: When we speak about more than one person and one thing, we use the noun in plural form. Mass Nouns In linguistics, a mass noun, uncountable noun, or non-count noun is a noun with the syntactic property that any quantity of it is treated as an undifferentiated unit, rather than as something with discrete subsets. Non-count nouns are distinguished from count nouns. Given that different languages have different grammatical features, the actual test for which nouns are mass nouns may vary between languages. In English, mass nouns are characterized by the fact that they cannot be directly modified by a numeral without specifying a unit of measurement, and that they cannot combine with an indefinite article (a or an). Count Nouns In linguistics, a count noun (also countable noun) is a common noun that can be modified by a numeral and that occurs in both singular and plural form, as well as co-occurring with quantificational determiners like every, each, several, etc. A mass noun has none of these properties. It can't be modified by a numeral, occur in singular/plural, or co-occur with the relevant kind of determiner. Possesive forms of nouns How do I make the possessive form of a noun? The possessive of singular nouns ending in s, including nouns ending in s, x, z, ch, or sh, is formed by adding 's, e.g., witness's affidavit. However, if the next word begins with s, then add only an apostrophe, e.g., witness' story. The possessive of singular nouns not ending in s is formed by adding 's, e.g., VIP's seat, baby's food. The apostrophe follows the s of a word with two sibilant sounds, e.g., Kansas', Moses'. The apostrophe is added for the possessive of a noun that is plural in form but singular in meaning, e.g., mathematics' formulas. The apostrophe follows the s for the possessive of plural nouns that end in s, e.g., girls' movies. For the possessive of a plural noun that does not end in s, add 's, e.g., women's rights. For singular proper nouns, add only an apostrophe for the possessive, e.g., Achilles' heel.
