	~~The~~ shape of an array is a [[vector]] of lengths of the array along each [[axis]]~~. The Shape function <code class="apl">⍴</code> is a [[monadic function]] which returns the shape of its argument array~~. The [[dyadic function]] [[Reshape]] ~~(<code class="apl">⍴</code>)~~ produces an array of the shape specified by its left argument.		{{Primitive\|⍴\|Shape}} is a [[monadic function]] which returns the ''shape'' of its argument array, namely a [[vector]] of lengths of the array along each [[axis]]. The [[dyadic function]] using the same symbol is [[Reshape]] which produces an array of the shape specified by its left argument.

	An array's shape may be any vector of nonnegative integers with length less than or equal to the [[maximum rank]]. The length of an array's shape is the array's [[rank]], and the product of the shape is its [[bound]]. If the shape is [[Empty array\|empty]] then the array is a [[scalar]].
