:''This article is about the items of an array. For the set function, see [[Membership]].
In the APL [[array model]], an '''element''' of an array is one of the values it contains. In [[flat array theory]] an element is a [[character]], [[number]], or [[box]], and cannot be manipulated directly within the language. In [[nested array theory]] each element of an array is another array, and an element of an array can be retrieved using the [[Pick]] function. [[Stranding]] forms a [[vector]] directly from its elements.
