ΕΦΙΑΛΤΗΣ
The word «ἐφιάλτης» originally described the demon that "leaps upon" the sleeper, causing suffocation and terror, and subsequently the painful experience of the nightmare itself. In Greek mythology, Ephialtes was one of the Giants, son of Poseidon and Iphimedeia (or Gaea), who, along with his brother Otus, the Aloadae, attempted to overthrow the gods. Its lexarithmos (1054) mathematically reflects the concept of pressure and excess.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, ἐφιάλτης primarily means "one who leaps upon, an assailant." This original sense is found in Homer (Odyssey 11.310) referring to the mythical Giant Ephialtes, one of the Aloadae, who, along with his brother Otus, was known for his excessive strength and his attempt to overthrow the Olympian gods. His name signifies his aggressive, conquering nature.
Subsequently, the word evolved to describe a spirit or demon believed to sit upon sleepers, causing them a sensation of suffocation, terror, and paralysis. This demonic entity was held responsible for bad dreams and nocturnal anxieties, a concept found in texts from Theocritus to Plutarch. Popular belief associated it with an invisible force that "leaps upon" a person during sleep.
Ultimately, ἐφιάλτης came to signify the painful experience of the bad dream itself, the nightmarish state, or the sensation of pressure on the chest during sleep, without necessarily referring to a demon. This meaning is evident in medical texts, such as those by Hippocrates, where it is described as a symptom or condition. Metaphorically, the word is used for any unpleasant, oppressive, terrifying, or insurmountable situation.
Etymology
From the same root ἁλ- of the verb «ἄλλομαι» derive many words related to the movement of leaping. Examples include the noun «ἅλμα» (a leap), the adjective «ἁλτικός» (skilled in leaping), as well as compound verbs such as «ἐφάλλομαι» (to leap upon), «καθάλλομαι» (to leap down upon), and «ἀφάλλομαι» (to leap off from). All these words retain the core meaning of sudden, dynamic movement.

Word Family
ἁλ- / ἄλλομαι (root of the verb ἄλλομαι, meaning "to leap, to spring up")
The root ἁλ- (or ἄλλομαι in the active voice) is an Ancient Greek root expressing the concept of sudden, dynamic movement, a leap or a spring. From this root derives a family of words describing various forms of this movement, whether as an action, a result, or a quality. Compounding with prepositions, as in the case of «ἐφιάλτης» (ἐπί + ἄλλομαι), enriches the meaning, giving direction or purpose to the leap.
