Arguments

sourceRequired: block <pos>, entity <target> or storage <id>.
pathOptional: NBT path, for example Health or Items[0].

get prints data (or one path of it), merge combines a compound into the existing data, modify sets, appends, prepends, inserts or merges at a path from a value, another source or a computed number, and remove deletes a path.
