How to say "permitted, lawful (halal)" in Arabic

Same root, opposite theological spin: the core sense of ḥ-l-l is 'to release, loosen, make non-sacred.' Hebrew took that toward חילול, desecration — stripping something of its holiness. Arabic took it toward ḥalāl, release from prohibition, i.e. permitted. One root, two ways of leaving the sacred zone.
