Bloody easy one holding you up? (3,5)
I believe the answer is:
red light
'one holding you up?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'bloody easy' is the wordplay.
'bloody' becomes 'red'.
'easy' becomes 'light' (similar in meaning).
'red'+'light'='RED-LIGHT'
Can you help me to learn more?
(Other definitions for red light that I've seen before include "Indication of immoral area" , "Stop signal" , "Danger signal" , "Warning signal" , "Don't go through it!" .)
