Plural of falsity; statements, beliefs, or things that are not true or are deceptive.
From 'falsity' with plural '-ies' ending. 'Falsity' itself comes from Latin 'falsitas' (state of being false) through Old French 'faussite.'
The plural 'falsities' is interesting—it suggests multiple distinct untruths rather than just 'falsehood' as a concept, which is why Dante used this word heavily when describing different types of lies in Hell.
