Allusion is commonly used in speech where it would be considered rude or otherwise socially hazardous to make direct reference.
The thing alluded to may require some form of prior knowledge. In this way, it can be used as a signal to friends whilst others may not understand what is being said.
Allusion uses the principle of association to connect a vague item to something more specific, or one clear item to another. In this way, when you start a commonly known phrase, the rest of the phrase is alluded to and may be left out.
Prose and poetry often make use of allusion, hinting at things that the reader may discover.
Allusion comes from the Latin word 'allsus' meaning to play with'.
