Last one. 30d Publication to pass over material (8) O - G - N - - I - Looks like ORGANDIE, but why?
29d Humorous dictum put relaives by marriage in changed position (10, 3) P - R - I - S - N - L - W Looks like PARKINSON LAW, again why?
Thanks for help.
30d A newspaper or magazine is sometimes referred to as an "organ". It's old-fashioned, but it's true. So, you get ORGAN and pass over, which is to die, thus ORGAN DIE.
Its usual here frameshift. You start to type when there are no answers. By the time you have finished and pressed submit answer you see all the others!
