open question(redirected from a open question)
An issue that cannot be readily resolved or decided. Whether veganism is good for your health is an open question—you'll get a different take depending on who you talk to.
An unresolved issue, one that has not been finally determined. For example, Whether the town should pave all the unpaved roads remains an open question. In the mid-1800s this term acquired a specific meaning in the British Parliament, that is, "an issue on which members may vote independently, without respect to their party affiliation."
