The advancements in technology created the need for new words. Even though these words conform to the standards of the English language, many people in the United States have no clue what they mean. One can speak English fluently and not know the meaning of software, byte, or a chat room. Upon hearing such words, one might even falsely assume that he is hearing a different language, but language promises its speakers the ability to invent and modify. Language can be used to promote individual expression.
Personalities can also affect a people's culture.
Gangs often create and perpetuate the use of slang words, which are sometimes integrated into the culture of the entire group. Certain words and expressions are used to identify members of a certain group and serve to build cohesiveness among group members. Language allows this expression through its ability to adapt to personal and group needs. Language gives humans the ability to communicate the past, present, and the future. A people's culture passes from one generation to the next due to language's ability to communicate the past, present, and future.
