Drop[list, n]

returns list with the first n elements removed.

Drop[list, -n]

returns list with its last n elements removed.

Drop[list, {m, n}]

returns list with elements m though n removed.

Drop up until the third item from the beginning of a list:

• • Drop[{a, b, c, d}, 3]

Drop until the second item from the end of that list:

• • Drop[{a, b, c, d}, -2]

Drop from the second item to the second-to-the-end item:

• • Drop[{a, b, c, d, e}, {2, -2}]

Drop a submatrix:

• • A = Table[i*10 + j, {i, 4}, {j, 4}]

• • Drop[A, {2, 3}, {2, 3}]

Dropping the 0th element does nothing, and returns the list unmodified:

• • Drop[{a, b, c, d}, 0]

Even if the list is empty:

• • Drop[{}, 0]
