A state of delirium or wild frenzy, sometimes used poetically or archically to describe confused excitement or madness.
From de- (intensive prefix) + delirium (Latin for madness, literally 'off the furrow' from de- + lira, furrow). The doubled form is rare and poetic, appearing occasionally in 19th-century literature as an exaggerated or theatrical version of delirium.
This word is so archaic that even modern dictionaries barely recognize it—it's the kind of dramatic, theatrical word a Victorian novelist might use when characters go absolutely bonkers, turning regular delirium into 'deliliria' for extra chaos.
