I am creating some software that has the concept of truncating a one-dimensional array from either the left or right end. I'm happy using the word truncate to describe lopping off the rightmost end of the array, but it doesn't feel right to use this word when removing array elements from the beginning.
I've considered left-truncate but that seems to have another meaning in statistics.
"I've (left-truncated) the array [1,2,3,4,5] and am left with [3,4,5]"
