To pop the nth element from an array in Perl, the correct method is to use the `splice` function. The syntax is `splice @array, OFFSET, LENGTH`, where OFFSET is the index of the element to remove, and LENGTH is the number of elements to remove. For example, to remove the 3rd element from the array `@array=(a,b,c,s,d,f,g)`, you would use `splice @array, 2, 1`. This method effectively modifies the original array by removing the specified element. The term "pop" typically refers to removing an element from a stack, which can lead to confusion if not clarified.
