Strange paradigm about hospital displaying body part (9)
I believe the answer is:
diaphragm
'body part' is the definition.
('diaphragm' is part of 'body')
'strange paradigm about hospital' is the wordplay.
'strange' is an anagram indicator.
'about' indicates putting letters inside.
'hospital' becomes 'h'.
'paradigm' anagrammed gives 'diapragm'.
'diapragm' going around 'h' is 'DIAPHRAGM'.
'displaying' is the link.
(Other definitions for diaphragm that I've seen before include "Thin dividing membrane" , "Midriff" , "Partitioning membrane" , "Flexible membrane" , "Partition between thorax and abdomen" .)
