Really enjoy getting first look over brief (4)
I believe the answer is:
love
'really enjoy' is the definition.
(I've seen this in another clue)
'first look over brief' is the wordplay.
'first look' becomes 'l' (1st letter of 'look').
'brief' means to remove the last letter (a shorter or briefer version of the word).
'over' with its last letter taken off is 'ove'.
'l'+'ove'='LOVE'
'getting' acts as a link.
(Other definitions for love that I've seen before include ""Tell me the truth about ___" (Auden)" , "All you need, according to the song" , "Adore, cherish" , "Vole (anag.)" , "Zero score (it's all you need)" .)
