Check about test case finally and investigate again (2-7)
I believe the answer is:
re-examine
'investigate again' is the definition.
(I've seen this before)
'check about test case finally' is the wordplay.
I cannot really understand how this works, but
'check' could be 'examine' (I've seen this before) and 'examine' is located in the answer.
'about' could be 're' ('re' means regarding or about) and 're' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for re-examine that I've seen before include "Investigate again" , "Study further" , "Look at again" .)
