One contributing doggedly to security? (3)
I believe the answer is:
cur
'one contributing doggedly' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'security?' is the wordplay.
'CUR' is hidden within the letters.
But, I am not sure how the hidden word is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for cur that I've seen before include "Lowly dog" , "Scoundrel; mongrel dog" , "Miserable dog" , "Despicable person" , "Base fellow" .)
