Inviting mockery, perhaps, no good for Charlie’s evening out! (7)
I believe the answer is:
ironing
'out' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ironing that I've seen before include "Making clothes smooth" , "Laundry work" , "Laundry job" , "Smoothing with heat" , "A housework chore" .)
