v. to escape
n. escape

Fent ni filok.
(You) shall not escape.
(Nahkriin, 000E16F8)

Nau daar revak golt drey Freda zahrahmiik ek Laas, ful tol ek pogaan kiir filok, ahrk osos sul qahnaar ek hokoron.
On this sacred ground did Freda sacrifice her Life, so that her many children might escape, and some day vanquish her enemies.
(Word Wall for Laas, Aura Whisper)

Unlike bovul ‘to flee’, does not connotate terror or cowardice; finding safety, respite.

May be from lok ‘sky’ in association with freedom and openness.
