Copyable is an option for Cell which specifies whether a cell can be copied interactively using the front end.
Even with the setting Copyable->False, the expression corresponding to a cell can still be read into the kernel using NotebookRead.
With Copyable->False set at the notebook level, no cells in the notebook can be copied interactively in the front end.
See Section 2.11.9.
