APL is A Programming Language, derived from a mathematical notation developed at Harvard in the 1950s and published in a book of the same name by [wiki:Kenneth_E._Iverson Kenneth E. Iverson].
It is distinguished by
- extreme terseness
- defining its primitives over arrays
the use of [:SpecialCharacters:special glyphs] to denote its primitive functions
- extensive use of higher-order functions
The original APL\1130 spawned [:/AplsAndRelatedLanguages many APLs and related languages]. It has also exercised a strong influence on [wiki:WikiPedia/Functional_Programming functional programming].
