I need some help on the last piece of this crossword. I'm assuming 1ac 'Sponging Zoroastrian concealing a nerve problem' is PARASITIC. Assuming this is correct then 5d 'Grant aid to enclose top of this support' (8) I have C?R?A???. Then 19ac 'Made of glass, it's thrown over suit' (8), I have ???R?O?S. Thanks in advance
