Drop[list, 
m, n
] gives list with elements m through n dropped.
Drop[list,

] gives list with elements m through n in steps of s dropped.
Drop[list, 
, 
, ... ] gives a nested list in which elements specified by

Drop uses the standard sequence specification (see Section A.3.5).

Drop[
a,b,c,d,e

Drop can be used on an object with any head, not necessarily List.
Drop[list,
