The quality or state of being able to be arraigned, or the legal condition of being subject to formal charges and court proceedings.
From 'arraignable' (able to be arraigned) + '-ity' (suffix forming abstract nouns). Arraign comes from Old French 'arainier' meaning to accuse or call to account in court.
Arraignability is a legal concept that determines whether someone has sufficient legal standing to face charges—it's what decides if you can even be brought before a judge, making it one of the earliest gatekeepers of justice.
