Hairy swinger opening hotel (5)
I believe the answer is:
sloth
'hairy swinger' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'opening hotel' is the wordplay.
'opening' becomes 'slot' (slot is a kind of opening).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'slot'+'h'='SLOTH'
Can you help me to learn more?
(Other definitions for sloth that I've seen before include "Idleness" , "Torpor" , "Sinful" , "Indolence" , "One's often suspended from tree" .)
