Much research has highlighted differences in language use between the social classes, with the vocabulary spoken in lower-class homes being ‘deficient’. Lower-class families are more likely to communicate by gestures, single words, disjointed phrases and reliance on slang. As a result, their children fail to develop the necessary language skills. They grow up incapable of abstract thinking and unable to use language to explain, describe, enquire or compare. Because of this, they are unable to take advantage of the opportunities that school offers.
