Consider resit initially given poor grade (6)
I believe the answer is:
regard
'consider' is the definition.
(I know that consider can be written as regard)
'resit initially given poor grade' is the wordplay.
'initially' suggests taking the first letters.
'given' says to put letters next to each other.
'poor' indicates anagramming the letters.
The initial letter of 'resit' is 'r'.
'grade' with letters rearranged gives 'egard'.
'r'+'egard'='REGARD'
(Other definitions for regard that I've seen before include "Think of" , "Deem, view" , "Look at - estimation" , "Former gold coin" , "Behold" .)
