You landed here in Orly? Wicked (7)
I believe the answer is:
vicious
'wicked' is the definition.
(similar in meaning)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for vicious that I've seen before include "Marked by deep ill will" , "Deliberately cruel or violent" , "Brutal, savage and dangerous" , "Deliberately harmful and savage" , "Strongly spiteful and dangerous" .)
