Hot and humid scullery vacated by group inside (6)
I believe the answer is:
steamy
'hot and humid' is the definition.
(I've seen this before)
'scullery vacated by group inside' is the wordplay.
'vacated' means to remove the middle letters (internal letters vacate the word).
'by group' becomes 'team' (group of people. I am not sure about the 'by' bit.).
'inside' means one lot of letters goes inside another.
'scullery' with its centre taken out is 'sy'.
'sy' placed around 'team' is 'STEAMY'.
Can you help me to learn more?
(Other definitions for steamy that I've seen before include "Erotic; like vapour" , "Torrid, erotic" , "Salacious" , "Vaporous: lustful" , "Erotic, sexy" .)
