## AI Etymology
Delirious is from Latin delirus ('crazy, deranged'), from delirare ('to be deranged'), literally 'to deviate from the furrow', from de- ('away from') + lira ('furrow, ridge'). The ancestry passes through Latin delirare and Latin lira. The prefix de- often marks removal, reversal, or downward motion in Latin formations, helping to explain the word's surface structure. In present use as an adjective, it means "in a confused, excited state; wildly ecstatic", keeping the historical formation close to the word's ordinary semantic work. Related words include delirium and delire; derived forms include deliriously and deliriousness.
