Wicked thing that a person hides (5)
I believe the answer is:
taper
'wicked thing' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'that a person hides' is the wordplay.
'hides' indicates the answer is hidden within the clue.
'TAPER' is hidden in the letters of 'that a person'.
Can you help me to learn more?
(Other definitions for taper that I've seen before include "Thin candle, spill" , "Gradually reduce - spill" , "Thin progressively" , "Get thinner - lighter" , "Narrow towards the end" .)
