Morally allowed or acceptable; not forbidden by moral principles. An action that one may perform without violating moral duties, though it may not be morally required.
From Latin 'permittere' (to let through, allow) plus the suffix '-ible.' The concept is central to deontic logic and moral theory, distinguishing what is allowed from what is required or forbidden.
Permissible actions occupy the moral 'gray zone'—they're not wrong, but they're not necessarily praiseworthy either. It's like having a moral hall pass that says 'this is okay to do' without saying 'you should definitely do this.'
