Slang: informal language, social identity, and linguistic change

Characteristics and functions

Slang usually shares several qualities: informality, high expressiveness, rapid innovation, and social indexing (signalling membership in a group). It often relies on metaphor, abbreviation, sound play, and shifts in meaning. Slang can be used to create in-group exclusivity, to avoid eavesdropping by outsiders, or simply to add color and emotion to conversation. It is different from technical language, or jargon, which seeks precision within a field; for a comparison of these concepts see jargon and ordinary language.

History and social context

Words now considered standard sometimes began as slang, and many slang terms move into accepted usage over time. Language contact, social stratification, migration, urban life, and media all accelerate the spread and adoption of slang. Historical episodes—such as the replacement of certain Old English words with Latinate terms after the Norman conquest—illustrate how elite preferences can shape which words are considered polite or proper; a related discussion appears at language contact and borrowing. Social power and attitudes toward class or ethnicity often influence whether a variety of speech is labeled slang, correct, or vulgar; see broader commentary at language attitudes.

Uses, examples, and cultural influence

Slang appears in everyday talk, music, advertising, social media, and literature. It is a source of lexical innovation: new verb forms, noun senses, or idiomatic phrases can originate as slang. Examples familiar to many English speakers include informal greetings and contractions such as wassup ("what's up?") and reduced forms like dunno ("I don't know"). These items can spread rapidly through popular culture and digital platforms. For guidance on how slang enters mainstream vocabulary, consult popular media and lexicography.

Distinctions, stigma, and documentation

It is important to distinguish slang from related categories: colloquialism (everyday informal speech), dialect (systematic differences tied to region or community), jargon (specialised vocabulary for a profession), and profanity or taboo language (words that offend or are restricted in polite contexts). Attitudes toward slang range from celebration of expressive creativity to concerns about clarity or respectability. Dictionaries and corpora increasingly document slang; efforts to track usage can be found at resources like lexical databases and historical archives at language history collections.

Practical notes and further reading

When using or studying slang, consider audience, register, and purpose. Educators, writers, and communicators weigh the energetic appeal of slang against potential misunderstandings or social judgments. Linguists analyze slang to learn about semantic change, social networks, and creativity in language; see studies and introductions at sociolinguistics and lexical innovation. For perspectives on etiquette, power, and language labeling consult language and power and historical treatments at ceremony and speech.
