Strange angle adopted by continent showing lack of feeling (9)
I believe the answer is:
analgesia
'lack of feeling' is the definition.
(inability to feel pain)
'strange angle adopted by continent' is the wordplay.
'strange' indicates anagramming the letters.
'adopted by' indicates putting letters inside (I've seen this in other clues).
'continent' becomes 'asia' (Asia is an example).
'angle' anagrammed gives 'nalge'.
'nalge' going inside 'asia' is 'ANALGESIA'.
'showing' acts as a link.
(Other definitions for analgesia that I've seen before include "Inability to feel pain" , "Absence of pain" , "result of medication?" , "Painlessness" , "Loss of pain" .)
