Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

no·to·ri·ous (nō-tôrē-əs)
Share:
adj.
Known widely and usually unfavorably: a notorious pirate; a region notorious for floods.

[From Medieval Latin nōtōrius, well-known, from Latin nōtus, known, past participle of nōscere, to get to know; see gnō- in the Appendix of Indo-European roots.]

no·tori·ous·ly adv.
no·tori·ous·ness n.

Usage Note: Although notorious and notoriety have been used in negative, positive, and neutral contexts since the 1500s, over the years, notorious (and to a lesser extent notoriety) has come to be used primarily in negative contexts, often with a connotation of wickedness or undesirability. In our 2011 survey, 81 percent of the Usage Panel accepted the sentence The region is notorious for its seismic disturbances, whereas only 26 percent accepted a sentence that used notorious in a situation where the circumstances for fame are positive: She is notorious for her excellent standup comedy routines. The Panel is somewhat more willing to accept notoriety in a positive context: almost half (45 percent) approved of the sentence His success on college campuses brought him enough notoriety to release a greatest hits CD.
