The act of forbidding; a prohibition or the state of being forbidden.
From 'forbid' + '-ance' (noun suffix from Latin -antia, meaning state or condition). This is the standard modern form replacing older 'forbidal.'
Legal and formal English prefers '-ance' and '-ence' suffixes for creating nouns (forbiddance, tolerance, evidence), which is why these words sound more official than their '-al' alternatives.
