In sociolinguistics, language is influenced by various social factors like class, education, gender, and age. These social dialects can affect how students speak in a classroom with diverse backgrounds. Changes in language are sometimes shared between English and Spanish speakers, like new names for things. Understanding social influences on language is important for lexical analysis and can help future English teachers understand differences in students' speech. Standard language is constantly evolving but educated or socially accepted forms don't change as quickly.
