Stuck on two that cross in the NE, and can't see the parsing of a third (if I have the right answer). Any
hints please?
8a Reserved a sponge without a home (5)
???O?
4d Stinking holiday without grass? (4)
???D
Also 22a
Even turned to disengage (4)
U?D?
There's seems to be only one sensible answer, with a slightly iffy definition, but what's the parsing?
