Fears detention possibly, or an expulsion of sorts? (14)
I believe the answer is:
defenestration
'an expulsion of sorts?' is the definition.
I can't tell whether this definition defines the answer.
'fears detention possibly' is the wordplay.
'possibly' indicates an anagram.
'fears'+'detention'='fearsdetention'
'fearsdetention' is an anagram of 'DEFENESTRATION'.
'or' is the link.
Can you help me to learn more?
(Other definitions for defenestration that I've seen before include "projected through lights" , "Act of throwing out of a window" , "Opening extraction" , "Ejection from a window" , "Act of ejecting someone through a window" .)
