Obscenity
noun /əbˈsiː.nɪ.ti/ — Language or material that is offensive or shocking by social standards.
Definition
Material or language that violates accepted standards of decency — typically involving sexual content or deeply offensive speech. Obscenity is legally defined in many jurisdictions but resists stable definition: as a US Supreme Court justice famously said, 'I know it when I see it'.
Beyond the definition
Obscenity is the speech act that most directly confronts taboo — and in doing so, reveals what a society has decided must not be said plainly. What is obscene tells you what a culture wishes to be invisible.
Origin & history
From Latin 'obscenitas' (indecency); from 'obscenus' (ill-omened, disgusting, obscene). Something that confronts filth or ill-omen.
