Ushered outside again and it was wet (8)
I believe the answer is:
showered
'and it was wet' is the definition.
I can't judge whether this definition defines the answer.
'ushered outside again' is the wordplay.
'ushered' becomes 'showed' ('show' can be a synonym of 'usher').
'outside' means one lot of letters goes inside another.
'again' becomes 're'.
'showed' going around 're' is 'SHOWERED'.
Can you help me to learn more?
(Other definitions for showered that I've seen before include "had a clean" , "Washed oneself in sprayed water" , "Stood under a spray of water" .)
