Glaringly obvious (7)
I believe the answer is:
blatant
'glaringly obvious' is the definition.
(blatant means very obvious)
This is the entire clue.
(Other definitions for blatant that I've seen before include "Far from subtle" , "Overt and shameless" , "Open, unashamed" , "Unashamed, flagrant" , "Very noticeable and obtrusive" .)
