Morning exam is quite unethical (6)
I believe the answer is:
amoral
'quite unethical' is the definition.
'amoral' can be an answer for 'unethical' (I've seen this before). I'm unsure of the 'quite' bit.
'morning exam' is the wordplay.
'morning' becomes 'am' (as in 12:00 AM).
'exam' becomes 'oral' (spoken academic test).
'am'+'oral'='AMORAL'
'is' is the link.
Can you help me to learn more?
(Other definitions for amoral that I've seen before include "Having no code of ethics" , "Without ethics" , "without guiding principles" , "Lacking spiritual values" , "Shameless" .)
