Conspicuous-looking daggers (7)
I believe the answer is:
glaring
'conspicuous' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for glaring that I've seen before include "Blatant" , "Dazzlingly bright" , "Angrily staring" , "Looking daggers; obvious (error)" , "Dazzling" .)
