A student carrying guns — shocked (7)
I believe the answer is:
alarmed
'shocked' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'a student carrying guns' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'carrying guns' becomes 'armed' (I've seen this in another clue).
'a'+'l'+'armed'='ALARMED'
Can you help me to learn more?
(Other definitions for alarmed that I've seen before include "Terrified" , "Frightened, disturbed" , "as a door handle may be?" , "Flapping" , "Given a turn" .)
