I'm struggling a bit with this one, but especially two clues.
1 down: Men oddly request reduced sums of money (4) _N_ _
18 down: One is overwhelmed by corrupt, loose living (9) R_K_ _ _ H_T
I've got more letters but I'm not sure they are correct
Thanks in advance

1d) MNAS = m(e)n + as(k)

18 D is one of the themed answers - what you put in isn't a real word. The answer to the clue itself is a 4 letter word - then you insert a word, as per the theme.

ah, that explains why i can't find anything in Chambers that fits

18 down. This is a thematic clue. The actual answer is only 4 letters, one letter of which is replaced by aparticular item in keeping with the theme of the crossword.y our letters are right so far.

Thank you all, that has given me a chance to solve it, though I've still got a long way to go!
