Young people use specific language and speech to express their group identity and to show that they are different in certain situations and to point out their uniqueness and individuality. Differences between generations are visible in the language elements often used by different age groups. The use of slang, colloquialisms, foreign words and vulgarisms are the most prominent features of young people's language. Urban dialects are created by intertwining regional, in other words dialectal features with elements of standard language, under the influence of social factors and suppress less prestigious rural speech characteristics. Young people mainly use words and expressions from popular culture that spread through social networks, media, music and movies, they expand their vocabulary with foreign expressions to differ from the older age group. Dialectology as a branch of linguistics that studies and describes dialects and local dialects of a language, also provides many non-linguistic conclusions: about the origin of the population, about relations between the population, about conditions and way of life, about connections in cultural events.
