Word soul

The Modern English word soul, derived from Old English sáwol, sáwel which means immortal principle in man, was first attested in the 8th century poem

Beowulf v. 2820 and in the Vespasian Psalter 77.50 . It is cognate with other German and Baltic terms for the same idea, including Gothic saiwala, Old High German sêula, sêla, Old Saxon sêola, Old Low Franconian sêla, sîla, Old Norse sála and Lithuanian siela. Deeper etymology of the Germanic word is unclear.

The original concept behind the Germanic root is thought to mean “coming from or belonging to the sea (or lake)”, because of the Germanic and pre-Celtic belief in souls emerging from and returning to sacred lakes, Old Saxon sêola (soul) compared to Old Saxon sêo (sea).
