Ooops, you found a broken link.
I’m so sorry!
It’s no fun getting lost, and there’s not much I can do
to help — unless you’d like to drop me a line.
“The word “lost” comes from the Old Norse “los,” meaning the
disbanding of an army, and this origin suggests soldiers
falling out of formation to go home, a truce with the wide world.
I worry now that many people never disband their armies,
never go beyond what they know. ”
The etymology is incorrect.
The Old Norse los is more a “cousin” to the Old English verb forleosan,
which is the ancestor of the Old English forms that gave rise eventually to the English verb lose.
(You can trace the details here.)
But the writing is quite nice.
