In order to understand how language variation descriptors are used, we first must understand what language .
variation is. We can say that the U.S. is linguistically diverse because of the multitude of languages spoken here, .
but we can also find diversity within these languages. All languages have both dialectical variations and registral .
variations. These variations, or dialects, can differ in lexicon, phonology, and/or syntax from the Standard .
Language that we often think of as correct Language, although they are not necessarily less proper than, say, .
Standard English. It depends on where, by whom, and in what situation the dialect is used as to whether or not it .
is appropriate.
Most people are familiar with regional dialects, such as Boston, Brooklyn, or Southern. These types of .
variations usually occur because of immigration and settlement patterns. People tend to seek out others like .
themselves. Regional variations tend to become more pronounced as the speech community is more isolated by .
physical geography, i.e. mountain ranges, rivers. Linguists have done extensive studies on regional dialects, .
producing detailed Linguistic Atlases. Many linguists can tell where a person is from just by knowing whether a .
person carries groceries home from the supermarket in a paper bag or from the grocery store in a paper sack (Yule .
184). And the person who comes home from the supermarket with a paper sack serves to remind us that .
language variation is not a discrete, but rather a continuous variable. Characteristics of the dialect are more .
pronounced in the center of the speech community and tend to be less discernible at the outer boundaries, where .
they often overlap other regional dialects.
Within, and between, these regional variations we find the social dialects. The primary social factors that .
influence dialects are class, education, occupation, ethnicity, sex, and age (Ferguson 52, Yule 191).
