Today's word of the day is aliusitas. It apparently is a certian kind of alietas. I am not exactly sure what kind. As one might surmise, it comes from the 14th century theologian and Scotist philosopher Peter Thomae, from his Formalitates seu Quaestiones de modis distinctionis q.5 a.4. Here it is, in all its glorious context.
Omnis enim alietas vel facit aliud et sic potest vocari alietas aliuditatis vel alium et sic alietas aliusitatis; et ista alietas est proprie inter diversa supposita sicut prima inter diversas essentias; vel facit alterum et haec est alietas alteritatis quae est non alietas essentiae nec suppositi sed alicuius accidentalis dispositionis.
Honestly, I don't even know how to translate this. "For otherness either makes another and so can be called otherness of otherness, or other, and so otherness of [some other kind of otherness]; and that otherness is properly between diverse supposits, just as first among diverse essences. Or it makes an other, and this is otherness of otherness which is not otherness of essence or supposit but otherness of an accidental disposition.
Admittedly, it is utterly out of context.
