Synonym discussion
Sense: noun/1
These nouns all point to a problem with rules, but they are used in different settings. 'Unlawfulness' is formal and legal: it asks whether an act, order, search, detention, or policy fails to conform to law. 'Illegality' is the more common everyday noun for the same basic idea. 'Wrongfulness' can be legal or moral, so it is wider and less precise. 'Invalidity' is narrower: it usually means that a document, decision, or legal act has no force because it does not meet required rules.
Common collocations
Etymology
Formed from 'unlawful' plus the noun-forming suffix '-ness'. The base 'lawful' comes from 'law' plus '-ful', while the prefix 'un-' gives the opposite meaning. The whole word therefore names the state or quality of being not lawful.
