indesiderati

Indesiderati is an Italian term used as an adjective and as a noun to refer to people or things that are unwelcome or not desired. The masculine plural indesiderati and the feminine plural indesiderate agree with the nouns they modify; the feminine singular indesiderata is used for feminine singular nouns. The concept covers a broad range of unwanted items, from physical objects to undesirable outcomes.

From the prefix in- plus desiderato, indesiderato meaning "not desired." The word is standard in Italian and found in formal and informal contexts.

In usage, indesiderati appears in many collocations: contenuti indesiderati (unwanted content such as spam or clickbait); contatti o telefonate indesiderati (unwanted contacts or calls); effetti indesiderati (adverse effects) in medicine and pharmacology; esiti indesiderati (unwanted outcomes) in research and policy. The term can also describe people who are not welcome in a particular setting, as in gli indesiderati, though this usage is more context-dependent and sometimes pejorative.

Related terms include indesiderata and indesiderato as inflected forms, and synonyms such as sgradito, non voluto, or indesiderato in negative contexts. In information technology, "undesirable" content is often labeled as junk or spam, with "spam" and "contenuti indesiderati" used interchangeably in many interfaces.
