Olympos

Also it might've come from Sanskrit
"aalayа" — abode, or "ālamb" — to hang on, to support.
From Greek "λάμπω" — to shine.

The name Olympos remains the same in contemporare greek. (not only ancient Greek). Derives from Greek roots: OL-MP > ol means bright, shiny and mp< βασις=base, solid ground.

The word is believed to have origins in Pelasgian, a pre-Indo-European language.
