LiisIf it's supposed to be Have as in "I have a gun" then it's using the wrong form. Lost is a synonym to Was. Whenever I mean "I have a gun", I translate it from "I Own a gun" Own being Laav.
That's a great point. If the distinction between canon and non-canon makes a difference, piraak would be the canon option. So either kolaav or kopiraak.
