Plural of delirium; multiple instances or states of delirious confusion.
Latin plural form of 'delirium', the neuter nominative/accusative form, retained in English medical terminology as the preferred plural in clinical contexts.
Doctors still prefer 'deliria' as the plural in formal medical writing, giving it a classical gravity—patients suffering from 'deliria' sounds more serious than 'deliriums,' which is partly why the Latin plural has survived.
