Can anyone - please - help me get going? So far I've solved only 8 or 9 clues.
21 A. Pacifist and bishop delight in interdependence (11) -----l--i--
30 D. Symbol is up and down (6) s---l--
(I keep seeing 'scales' - am I way off track?)
It isn't scales. You will see that 29ac is a plural word, and so probably ends in s. The construction of 30 d _is up, and then a word for down, in the sense of depressed.
